Seeking Specialist Insights on Persistent Health Issues
**I am reaching out for expert guidance regarding potential infections or parasitic infections.** For more than two and a half years, my family and I have been on a quest to identify the source of a troubling health condition characterized by significant weight loss and a variety of vague symptoms. Initially, due to heightened anxiety, medical professionals were concerned about cancer, which possibly misdirected focus away from a potential infectious—particularly parasitic—origin. During this time, I have been assessed by a multitude of specialists, yet a definitive diagnosis remains elusive. My primary care physician has indicated that there are no further tests to conduct, compelling me to investigate on my own through medical literature and AI resources. Presently, I am increasingly alarmed as it appears we are confronting a progressive and possibly infectious condition that has persisted for over two years and is now impacting nearly our entire household. Symptoms are present in five out of six family members, including two children aged two and six, with the sixth member also under consideration. Let me outline the developments and emerging concerns. **Symptom Progression:** Initially, I exhibited symptoms, which later manifested in our younger son (after his birth, just a few months later) as he experienced weight loss, lack of growth, pallor, thin skin, and recurrent diarrhea or undigested food. He is currently under the care of a pediatric gastroenterologist who has only conducted celiac disease testing without pursuing further investigations—for instance, parasitological assessments. Despite being on Nestlé Resource nutrition for over a year, there has been no improvement in his condition. Our older son (6) has shown signs of lethargy, fluctuating appetite (first low, then higher, mirroring my experiences), and changes to his stool—these are now yellow, mushy, oily, and more frequent. While physical transformations in him are less apparent, perhaps only noticeable through dry skin and persistent tiredness, his situation concerns me. My wife has begun to show symptoms as well, including mild weight reduction, ongoing fatigue, headaches, and aches in her muscles and joints. Although her weight change is subtle due to her naturally slender physique, she reports experiences akin to my own, including episodes of hunger soon after meals, sometimes even at night. It is worth mentioning that our dietary habits are varied—we consume both meat and vegetables, as we live in a rural area and maintain a garden with fruits and vegetables, avoiding any restrictive diets. What troubles me most is my father’s rapid weight loss of 6 kg within a brief span of 2 to 3 weeks, which he has been unable to regain. Even after undergoing gastroscopy, colonoscopy, and MRI, no underlying issue was identified, and the weight loss is notably striking, exacerbated by age-related skin changes since he is 64 years old. **Considerations and Hypotheses:** Given the symptoms and the familial spread of this condition, I have a strong suspicion of chronic giardiasis (*Giardia lamblia*), though I also consider the possibility of other parasites such as *Cryptosporidium*, *Blastocystis hominis*, *Toxocara*, and *Strongyloides stercoralis*, not to mention diseases like brucellosis. My background includes rural life in Europe, working on a farm with various animals like chickens, donkeys, and cats. Though I didn’t work directly with the animals, the potential for zoonotic transmission exists, especially since we have a dog that roams both inside and outside the house, coupled with my prior exposure to soil from areas with animals, suggesting a possible intestinal parasite or an intracellular bacterial infection. One test for *Giardia* in a stool sample returned negative, though I am aware of the intermittent shedding of cysts that can lead to false negatives. **Symptoms Across Family Members:** - **Chronic gastrointestinal issues**: bloating, oily or mushy stools (Bristol types 5–6), diarrhea - **Unexplained weight loss and growth failure in children** - **Skin changes**: dryness, thinning, and wrinkling; hair and body hair loss - **Hyperhidrosis**, particularly noticeable in armpits and feet - **Malabsorption of fat-soluble vitamins** (A, D, E, K), leading to nutrient deficiency manifestations: fatigue, brittle nails, dental deterioration despite maintaining oral hygiene, and skin that is dry, pale, and wrinkled - **Elevated cholesterol and triglycerides** despite malnutrition, potentially indicating altered metabolism of lipids - **Joint discomfort**: crepitus and sensations of instability, likely related to compromised collagen synthesis - **Children** exhibit inconsistent appetites, developmental delays, paleness, and fatigue - **Temperature regulation shifts**: episodes of chills without fever or sudden sensations of heat **Epidemiological Observations:** - Symptoms have manifested in all household members over the past 2.5 years, though not simultaneously - Our dog may serve as a potential vector for disease - There have been no travels to high-risk locations - Life in rural settings with animal interactions - Other systemic conditions have been ruled out (such as HIV, hepatitis, celiac disease, Crohn’s, etc.) **Further Diagnostic Avenues to Explore:** - Protozoal infections: *Giardia lamblia*, *Blastocystis hominis*, *Cryptosporidium spp.* - Zoonotic diseases: *Toxocara canis*, *Brucella spp.*, *Leishmania infantum* - Bacterial infections - Helminthic infections: *Strongyloides stercoralis*? - Tuberculosis if clinically indicated - Given the household-wide involvement and clinical presentation, could there be a case for initiating empirical treatment with antiprotozoals like metronidazole or nitazoxanide, despite *Giardia* not being confirmed through stool assays? Or is it imperative to conduct PCR-based diagnostics on the stool? I would greatly appreciate your insights regarding this summary, along with any diagnostic or therapeutic strategies you might recommend for this intricate, prolonged predicament. Thank you for your consideration and assistance in advance.

Thank you for sharing your family's complex health journey. Given the symptoms you've described and their prolonged nature, it’s understandable to be concerned about potential infections, particularly parasitic ones. Multiple members of your household experiencing similar symptoms does warrant a thorough investigation of possible infectious causes.
Key Points:
- Symptoms suggestive of malabsorption and potential infections such as giardiasis or other parasitic diseases.
- Family-wide impact necessitates a comprehensive approach to diagnosis and management.
- Continued vigilance and specific testing remain critical.
Explanation:
The symptoms you've outlined, including gastrointestinal distress (like oily stools), weight loss, and growth issues in your children, raise legitimate concerns about malabsorption or infectious processes. Chronic giardiasis is indeed a valid consideration, as other parasites could also be involved given your rural background and interactions with animals.
The negative stool test for Giardia can sometimes be misleading due to intermittent shedding, meaning further testing could be beneficial. A key point of concern is that persistent symptoms across your family suggest that this might not be a simple, isolated condition.
Next Steps:
-
Repeat Stool Testing:
- Request comprehensive stool tests that include multiple samples over a set period to increase the chance of detecting intermittent parasites. Ask for tests that evaluate for various gastrointestinal pathogens (including Giardia, Cryptosporidium, and other parasites).
-
Consider PCR Testing:
- If regular assays yield negative results, inquire about PCR testing for stool samples, which can provide more sensitive detection of certain parasitic infections.
-
Empirical Treatment:
- Discuss the possibility of starting empirical treatment for Giardia or other protozoal infections with your pediatric gastroenterologist or family physician, especially given the symptoms and family-wide presentation. Medications like metronidazole or nitazoxanide could be relevant, even before confirming a positive test.
-
Nutritional Support:
- Ensure that all family members maintain nutritional support, especially for the children. You might consider supplements for deficiencies in fat-soluble vitamins (A, D, E, K) if deficiencies are suspected, under guidance from a healthcare professional.
-
Routine Follow-Up:
- Regular check-ups with your GP and specialists (like a gastroenterologist) should be maintained to continually assess symptoms and adjust the management plan as necessary.
-
Assess Animal Factors:
- Evaluate your dog for parasites with a vet, as they could be potential vectors. Ensure that your dog is dewormed and that hygiene practices around pets and waste management are strictly followed.
Conclusion:
Continuing to pursue comprehensive testing and maintaining open communication with your healthcare providers about the family's evolving symptoms is paramount. In these complex and concerning situations, the persistence of symptoms and a family-centric approach is crucial. Please reach out if additional information or clarification is needed. Your family’s wellbeing is the priority, and gathering more data will hopefully lead you to the answers needed for effective treatment.

Navigating Health Concerns: A Young Woman's Plight with Chronic Migraines and Stress
To summarize a very complex situation, last spring in 2025 was exceptionally challenging for me. I faced overwhelming stressors, including family deaths, eviction, and my parents splitting up. This turmoil led to chest pains so severe that I had to visit the emergency room because I couldn’t breathe deeply without experiencing intense pain. The doctors attributed the issue to psychological causes, but I continued to suffer from pain and instances of fainting due to the stress, which worsened as yet another family member was diagnosed with cancer. My psychiatrist suggested medication, and I started on Lexapro and Concerta, which improved my condition somewhat, even though I remained fatigued and felt like I was merely surviving. By the end of August, I contracted a severe case of bronchitis that caused me to experience fevers even while doing laundry. It seemed I was verging on pneumonia, prompting the prescription of prednisone and other steroid medications. Thankfully, I began to recover quickly, but soon after, I was plagued by persistent headaches and an overwhelming sense of paranoia that someone was out to get me. After another emergency room visit, the physicians informed me that, although my symptoms—such as fever, intense pain, night sweats, sensitivity to light, ear pressure, and a stiff neck—were alarming, they were likely just severe migraines that should eventually fade. Unfortunately, they didn’t. I returned to urgent care for further treatment, received antibiotics, and was advised to consult a neurologist. While the antibiotics provided some relief, my symptoms intensified. My primary care physician eventually prescribed sumatriptan, a medication intended to alleviate migraine pain, but instead, it exacerbated the headache. For the next two to four weeks, I endured an exceptionally difficult time, facing numerous strange symptoms that felt worthy of immediate attention, yet each visit concluded with a migraine diagnosis and a waiting period for my neurology appointment. My frustrations pushed me to contemplate risky alternatives for relief, but I resisted, feeling utterly hopeless and unable to cope. I sought an ear, nose, and throat specialist to rule out sinus issues, which turned out to be fine. A painful spot under my jaw led me to suspect nerve involvement, and I visited the emergency room again due to experiencing stroke-like symptoms (including mild left arm weakness, extreme headache, and minor speech issues). Sadly, I was again told it was merely a headache, and the IV medications were ineffective. During my annual check-up, my primary care provider was unfamiliar with my ongoing issues but discovered an enlarged lymph node in the lower left side of my neck and a cyst on my thymus after conducting a soft tissue scan. She reassured me that there was no need for concern and suggested waiting for my neurology visit or getting my eyesight checked. Despite my yellower complexion, increasing stiffness, and joint pain, I accepted her recommendation. While I mentally adapted to the chronic pain, which was always present, it affected my ability to concentrate and engage in daily life. I tried consuming plenty of lemon juice and engaging in lymphatic drainage massages, which provided transient relief and halted my yellowing skin. Now, in the present, I've noticed a peculiar, raised red bump on the side of my foot. It’s hard, tender, and smaller than a dime, without any accompanying rash. It has persisted for a couple of weeks without causing pain while walking. Additionally, more lymph nodes in my neck have become swollen, I have experienced difficulty swallowing, and I occasionally choke on air. My lungs feel heavier with a diminished sense of smell, though I don't have the thick mucus typical of a cold. The headaches, however, are reemerging, sharper than before, which is a concerning development. Throughout all of this, my blood pressure has remained within a low yet stable range, and my blood tests and CT scans have shown no significant issues. I haven’t consumed anything excessively that might raise concern, including food or drugs. Am I truly facing a serious health crisis? Should I prioritize getting another appointment, or do I need to rush to urgent care? I'm scheduled to see the neurologist in about a month, and I'm wondering if I should ask my primary care provider for some preliminary tests like blood work or an MRI beforehand. If so, what specific questions should I prepare for my neurology visit? I believe the pain has a genuine physical basis, although my anxiety definitely amplifies the experience.
Injury to the Sciatic Nerve
At 25 years old and weighing 135 pounds, I am currently taking naproxen and Lyrica to manage my sciatic nerve injury. The pain in my right leg has made it incredibly difficult for me to remain upright. It’s been two weeks since I first sought treatment; I consulted a physician who advised medication and attended a physiotherapy session. Initially, I experienced some relief after the appointment, but unfortunately, the pain returned the following day—even the prescribed home exercises exacerbated my discomfort. Just yesterday, I attempted the cobra pose, along with the flossing technique, which only heightened my pain. I find it nearly impossible to stand for more than a few seconds before the discomfort becomes intolerable. Additionally, I have an appointment with an osteopath on Tuesday, but I can't shake off my worries— is it normal to still struggle with walking after two weeks? Although I am experiencing some numbness in my toes, I haven’t encountered any loss of bladder or bowel control, worsening numbness, or weakness in my legs, so I feel stable in that regard. Nonetheless, I fear the possibility of never fully recovering and being left with a lasting disability. The pain is overwhelming, adding to my anxiety about the future.
Inquiry Regarding Metronidazole Use for Recurrent Bacterial Vaginosis
I am a 32-year-old female, measuring 5 feet 5 inches tall and weighing 248 pounds. My current medications include Vyvanse at a dosage of 40mg, a medication for asthma, vitamin D, a 325mg iron supplement, and as of now, I am also taking amoxicillin to treat strep throat. I am about to begin using Metronidazole 0.75% Vaginal Gel, with a total of 70 grams available. The instructions indicate that I should administer 5 grams vaginally twice a day for seven days, followed by twice a week for a period of two months. During the initial treatment phase when I will apply the gel twice daily, I anticipate abstaining from sexual activity. However, once I transition to the twice-weekly application, is it permissible to engage in sexual intercourse? I would normally consult my physician about this matter, but she is currently unavailable, and the nurse is also out of the office, which is quite frustrating.
Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
