Experiencing Unexplained Hives After Poison Ivy Treatment
A 32-year-old woman, standing at 5’4” and weighing 160 pounds, has been on levothyroxine for a decade, a medication she believes is unrelated to her current skin condition. Her only known allergy is contact dermatitis resulting from poison ivy. She recently completed a 10-day course of Prednisone prescribed specifically for poison ivy dermatitis affecting her ankles. The blisters caused by the poison ivy have dried and mostly healed. However, two days post-treatment, she began to notice random bouts of itching occurring across various parts of her body, primarily affecting her upper arms and legs, along with occasional sensations on her torso. Interestingly, the itching seems more intense in areas where skin contacts skin, such as her inner thighs and elbows, though her shoulders have also been significantly itchy. Visually, there are no noticeable signs of irritation in the itchy areas. However, scratching has led to developing hives that last for an hour or two before fading away. This is her first experience with hives, leading her to question whether this reaction could be connected to her cessation of steroids or if it is a delayed systemic response from her earlier poison ivy exposure. Concerned, she wonders if this situation warrants any serious attention.

It sounds like you're dealing with some discomfort from unexplained itching and hives, which can be quite distressing, especially after your treatment for poison ivy. While it can be difficult to pinpoint the exact cause of your symptoms, there are a few important considerations and steps you can take.
Summary of Key Points:
- Your symptoms of itching and hives may be related to several potential causes, including a reaction to the poison ivy treatment, the recent cessation of steroids, or even new allergies.
- Monitoring and managing symptoms at home is crucial.
Explanation:
Hives (urticaria) can occur as a reaction to various factors like medications, allergies, environmental irritants, or even stress. In your case, since you just completed a course of Prednisone—a steroid often used to reduce inflammation—it is possible that your body is reacting as the medication leaves your system. Additionally, even after the initial rash from poison ivy heals, some individuals may still experience skin sensitivity or allergic reactions.
Your description of itching being more intense where skin contacts skin could suggest friction irritation or an allergic reaction as well. Since there's no visible rash most of the time, this makes it less likely to be caused by an ongoing dermatological condition like dermatitis.
Next Steps:
-
Avoid Triggers: – Try to identify and avoid any potential triggers for your hives, such as new detergents, lotions, or fabrics that might irritate your skin.
-
Over-the-Counter Antihistamines: – Consider using non-drowsy antihistamines like cetirizine (Zyrtec) or loratadine (Claritin) to help relieve itching and reduce the hives. Follow dosage instructions on the packaging carefully.
-
Cool Compresses: – Apply cool, damp cloths to the itchy areas to help soothe any irritation and reduce the urge to scratch.
-
Moisturizers: – Use unscented moisturizers to keep your skin hydrated, as this can help reduce itching and prevent further irritation.
-
Monitor Symptoms: – Keep a diary of your symptoms, noting when the itching occurs and any potential triggers. This information can be valuable if you seek further guidance later.
-
Watch for Severe Symptoms: – If you start experiencing severe symptoms such as difficulty breathing, swelling of the face or throat, or if the hives do not improve or worsen, consider seeking immediate medical attention.
If your symptoms persist beyond several days with no improvement or worsen, it may be helpful to reach out to a healthcare provider for a more specific evaluation. Understanding your body's response to medications, allergies, and environmental factors can greatly assist in managing these symptoms. Let me know if you need more information or assistance!

Understanding the Causes of Chronic Diarrhea
A 17-year-old male, who is in good physical condition and stands at 175 cm tall, has experienced challenges with chronic diarrhea since childhood. Remarkably, the issue ceased around the age of 12 without any discernible reason. However, during a trip to China in the summer of 2025, he suffered food poisoning, after which the diarrhea returned unexpectedly. He has noted an interesting pattern: the symptoms seem to manifest only when he experiences chills. Despite consulting his family doctor, he encountered a puzzling lack of answers regarding the recurrence of his symptoms. He has begun a treatment regimen, which, while seemingly effective, may be overly potent for his situation. He seeks insights into what might be the root cause of his condition and recommendations for appropriate medication. Interestingly, he believes he has no known allergies, but suggests there may be a hereditary component involved, as his mother experiences a milder form of the same issue. As for his nutritional habits, he maintains a well-rounded diet that incorporates a variety of foods without adhering to strict dietary categories such as vegan or vegetarian. His typical meals include an assortment of vegetables, various meats, and staples like bread, rice, or potatoes.
Urgent Help Needed for My Father's Health Crisis
I am reaching out in desperation regarding my father's health, as he's currently 58 years old and weighs approximately 60 kg. Is it feasible to manage chronic kidney disease stage 5 (CKD 5) solely through dietary changes and medications like Lasix? I implore you to read my entire account carefully. Recently, I encountered an individual who claimed to be a doctor, insisting that he has successfully treated numerous patients just by adjusting their diets. Unfortunately, my sister is starting to believe in these dubious claims, and this situation is jeopardizing my father's health. A detailed backstory follows. For an extended period, my father remained undiagnosed, but after some recent tests indicated alarmingly high creatinine and urea levels—initially recorded at 8.5—my mother, influenced by our Pakistani background and various conspiracy theories, opted against dialysis. Instead, she sought medication that would supposedly help maintain his health. At that time, my father exhibited no critical symptoms or unusual urine output. Months passed, and when his values failed to improve with medication alone, my mother turned to a homeopathic practitioner from another city, who claimed he had cured many CKD patients. Trusting his advice and spending a significant amount of money on his prescribed remedies, we adhered to a stringent dietary regimen that severely restricted protein intake. However, a month later, my father began experiencing serious breathing difficulties, finding it hard to catch his breath during routine activities such as walking or even standing. We conducted more medical tests and discovered that while his creatinine and urea levels had decreased (creatinine dropped from about 7 to 5), his hemoglobin level plummeted from 10 to 8, and fluid had accumulated in his lungs. Additionally, his feet were swollen, and he presented symptoms of exhaustion and shortness of breath, which we attributed to using only the homeopathic medications prescribed. We decided to discontinue this treatment due to my father’s worsening condition. Following this, my sister reached out to a new doctor, a recommendation from an Arabic community group; I’m uncertain of her qualifications. This new practitioner advised a complete diet overhaul, claiming that she, too, had cured CKD patients through dietary means. My sister, swayed by her assurances and the fact that she was not charging us, trusted this advice. This new dietary plan was seemingly extreme: it suggested a combination of proteins, fats, vegetables, and meats, while completely eliminating carbohydrates. The rationale was that carbohydrates contribute to insulin resistance—a significant concern since my father has had type 2 diabetes for over 20 years. Despite the doctor claiming that liver issues were stressing the kidneys and causing CKD, my father’s liver function tests indicated that his liver was functioning normally. I have attempted to engage my sister in discussions about her decisions, but she steadfastly adheres to her beliefs, often dismissing my concerns as unfounded. She believes that the medical system is merely profiting from keeping patients in a cycle of dependency on expensive treatments. I urgently seek guidance, as my father's well-being hangs in the balance. My attempts to reason with my sister have resulted in conflicts, and I seem to be viewed as the villain in this situation. A thorough, expert response would be greatly valued at this time.
Managing Severe Reactions to Black Henna: Steps to Heal Your Skin
On January 25, I decided to get a dragon design in black henna while in Boracay. Initially, I felt a slight tingling sensation on my skin, which later intensified to a burning feeling especially when exposed to sunlight. Upon returning home, my instinct was to scrub the henna off with soap. Unfortunately, this led to my skin becoming swollen, reddened, itchy, and even blistered. To soothe the irritation, I used a gentle cleanser like Cetaphil to cleanse the area thoroughly, ensuring it was completely dry afterward. Once dried, I applied a thin layer of petroleum jelly. I also began taking antihistamines such as Cetirizine or Loratadine, which provided some relief from the itching. Additionally, I tried to shield the affected area from sun exposure as much as I could. A few days into this routine, I introduced 1% hydrocortisone cream, layering it with petroleum jelly afterward. During my time in the city, I shifted to using Benadryl cream and continued taking antihistamines to diminish the itchiness, but I didn’t have any hydrocortisone cream available. Although the henna stain has nearly faded, the design has left a noticeable imprint on my skin. Once back home, I restarted my treatment by applying 1% hydrocortisone cream followed by a layer of Cetaphil PRO AD Derma Skin Restoring Moisturizer. I’m concerned about potential discoloration on my skin from this reaction. Currently, the skin looks flat and somewhat darker with slight bumps. I would greatly appreciate any advice on how to minimize hyperpigmentation and what treatments I can undertake to support healing.

Seeking Clarity on Persistent Symptoms and Possible Conditions
Greetings, medical professionals, I am a 19-year-old female struggling with ongoing physical discomfort and emotional challenges, and I am in need of your insights. Back in December last year, I underwent a thyroid ultrasound which detected five TI-RADS 5 nodules, each under 1 cm in size. Two of these nodules were located in the right lobe (measuring 0.2 × 0.1 cm and 0.9 × 0.1 cm) while the left lobe housed three smaller ones, the largest being 0.2 × 0.2 cm. Due to their diminutive dimensions, a repeat ultrasound was suggested for six months later instead of a biopsy. My thyroid hormone levels came back normal during this assessment. The imaging also indicated the presence of a submental lymph node, which has persisted for close to three years and initially prompted me to seek out imaging. It is both visible and can be felt. The report characterized it as unchanged, with a fatty hilum and an irregular shape, measuring 1.1 × 0.6 cm, and indicated that it seemed to be reactive in nature. Prior to discovering the nodules, I started experiencing back issues in May 2025. Initially, the discomfort was mild and localized to the left side, considered to be mechanical. However, the pain progressively worsened, spreading to both sides with the upper back predominantly affected on the left side, occasionally radiating to my neck. I also suffer from constant shoulder discomfort and my arms become sore easily, even from light activities. In subsequent months, I began to develop rashes, which I have documented in previous posts. The skin issues were initially misdiagnosed as scabies, but they worsened post-treatment. Although vasculitis was contemplated, my laboratory tests yielded normal results. A biopsy of the skin revealed psoriasiform spongiotic dermatitis and psoriasiform/nummular dermatitis. While the initial rashes responded to topical steroids, new ones are appearing on my legs, which I perceive as resembling petechiae—flat, tiny red spots that do not fade when pressed. In December of last year, I also became aware of swollen lymph nodes and widespread pain. The lymph nodes in question include: - Two nodes near the left lower back by the hip — these are painful and remain palpable after several weeks. - A node in the right groin/lower abdomen — initially painful, it has shrunk but still causes discomfort in the area. - A painless node in the left parotid area (cheek). - A painless node in the left axilla (armpit), which was first identified approximately eight months ago through a breast ultrasound, measuring 1.3 × 0.7 cm as a solid nodule, though the breast ultrasound returned negative results, and the lymph node size has remained stable. Additional symptoms include: - Radiating shoulder pain into the collarbone, - Intermittent pain in the calves and upper legs, - Unpredictable soreness and pain throughout my limbs (similar to post-exercise discomfort), - Random aches in my forearms, - Tingling sensations in my fingers, - An area in my left thigh that feels firmer than surrounding muscle, slightly elevated and noticeable to the touch. Pressing on it yields normal muscle sensation. My right thigh does not have this issue, leaving me uncertain if this is typical or concerning. My growing concerns revolve around potential serious conditions such as lymphoma or thyroid cancer due to the nodules observed. This situation has been incredibly taxing—I am lost on what symptoms should take priority or which specialists to approach. Additionally, I often feel brushed off by medical practitioners; whenever my symptoms are brought up, it appears they deem them insignificant and seem rushed. I am worried that there could be a significant underlying issue developing, especially as I've been experiencing increasing symptoms and a decline in my overall well-being in recent months. I understand that no diagnosis can be rendered over the internet, but I would greatly value your advice regarding: - The seriousness of my symptoms, - Potential tests or evaluations I should pursue, - The appropriateness of waiting six months for follow-up imaging. I appreciate your consideration and look forward to your guidance.
