Concerns About Chagas After Kissing Bug Bite
My husband, a 46-year-old white male weighing 235 pounds and standing 6 feet 5 inches tall, is on several medications including Wellbutrin (300 mg), Buspar (5 mg), Crestor (10 mg), a multivitamin, and omeprazole. He has been diagnosed with depression, anxiety, GERD, and high cholesterol. He quit smoking cigarettes in 2008 and uses marijuana infrequently, along with very occasional alcohol consumption. Recently, he was bitten by what we believe to be a kissing bug. This incident occurred two nights ago while we were in West Virginia, USA. He woke up scratching in the middle of the night and developed a growing welt on his lower hip area. Although he currently has no fever or other noticeable symptoms related to acute Chagas disease, the welt is hard, painful when touched, and continues to itch despite his attempts to scratch it. Since the bite, the swelling has increased. Upon changing the sheets, we discovered a dead bug, which confirmed our suspicion of it being a kissing bug. I am determined to take him to the doctor tomorrow, but I worry that our concerns may be dismissed. I want to ensure he receives blood tests for Chagas at least twice, as I am anxious about the timing of the tests being too early or too late, potentially resulting in a false negative. I need guidance on a few points: **What is the optimal timeframe for testing? What specific questions should I pose to the medical professionals? Is there any preventive treatment they can offer him in case the bug was a carrier of the parasite before the blood tests? What additional information should we be aware of?** Moreover, I would appreciate any advice on how to get the insect tested. I plan on reaching out to our local health department, but I'm concerned that we may not receive the attention we need due to our location not being considered a common area for such incidents. Articles I've read indicate that awareness of Chagas is low, as is the tracking of these cases, suggesting that it might be more widespread than known. While I understand that not all kissing bugs harbor the parasite and that transmission is not guaranteed, I am deeply worried about the possibility of missing a diagnosis and the opportunity to treat him during the acute phase should he indeed be infected.

It's understandable to be worried after a biting incident with a kissing bug, especially with the potential link to Chagas disease. Quick thinking and planning can help you navigate this situation effectively.
Key Points
- Timeframe for Testing: Testing for Chagas disease should ideally occur after a few weeks, as antibodies take time to develop. It's often recommended to test at 1-2 months post-exposure and again in 6 months to ensure accuracy.
- Questions for Healthcare Providers: You should ask about the likelihood of Chagas transmission from kissing bugs, what symptoms to watch for, and what the testing process will entail, including the possibility of starting treatment based on his symptoms.
- Preventive Treatment: Currently, there is no preventive treatment after exposure to a suspected kissing bug bite. However, the medical provider might monitor symptoms closely or consider treatment if there is a confirmed infection.
- Insect Testing: Contact your local health department or vector control agency to ask about testing the insect. They may have specific protocols in place, even in less common areas.
Explanation
Kissing bugs can transmit the parasite that causes Chagas disease when they defecate on the skin and the feces enter through the bite wound. Not all kissing bugs carry this parasite, but being proactive is key. The swollen, itchy area he has now is likely a reaction to the bite itself, and it’s advisable to keep it clean and avoid further irritation.
Next Steps
- Visit the Doctor: Make the appointment you have planned for tomorrow and be clear about your concerns regarding the kissing bug bite and Chagas disease. Share all details, including the time frame since the exposure and his current symptoms.
- Prepare Questions: Bring a list of your questions:
- What is the likelihood he could contract Chagas from this bite?
- When should we test for Chagas disease?
- Should he be monitored for any specific symptoms, and if so, which ones?
- What will happen if the tests come back positive?
- Document Symptoms: Keep a record of any changes in his symptoms (e.g., fever, fatigue, heart palpitations) to discuss with the doctor.
- Inquire About the Bug: Call the local health department to inquire about insect testing and follow their guidance on how to proceed.
- Consider Immediate Care for the Bite: To manage discomfort from the bite, he can use antihistamines like diphenhydramine (Benadryl) for itching or over-the-counter topical treatments.
This situation is understandably stressful, but being organized and informed will help ensure that he gets the care he needs. If you have any further questions or need more assistance, feel free to reach out.

Exploring Endolymphatic Hydrops: Could This Be My Condition?
34 years old / Female Current weight: 165 lbs Navigating the challenges of motherhood In early December 2025, I caught a cold. By mid-December, my right ear felt blocked, but I attributed it to the cold virus. As New Year approached, I experienced another cold, which coincided with an onset of ringing in my ears. Disturbingly, sounds started to seem altered from the affected ear, accompanied by a persistent fullness in that area. Additionally, I noticed twitching of my eye and swelling in the salivary gland on the same side. My primary care physician prescribed a decongestant and Flonase; however, because I am currently breastfeeding, I hesitated to take the medications as directed. On January 27, I was evaluated by an ear, nose, and throat specialist, who requested a hearing assessment the following day. The results indicated that I had sensorineural hearing loss affecting my low-frequency hearing range (250 Hz to 500 Hz). The doctor prescribed a steroid with the hope of addressing the issue promptly. Now on day 10 of steroid treatment, I have experienced significant relief. Remarkably, I've noticed a substantial amount of thick, putty-like mucus clearing from my nasal passages. The pressure in my ear has subsided, and sounds are returning to normal, though I still perceive a slight ringing — possibly just a touch of hearing loss remains. What concerns me is whether ongoing sinus congestion could be the root of these symptoms or if I might genuinely be dealing with endolymphatic hydrops. Notably, I have not experienced any episodes of dizziness. In the evenings, I tend to feel considerable pressure building on the right side of my head, almost as if my sinuses are becoming blocked once more. I would greatly appreciate any insights or advice on this matter, as I find myself in a state of uncertainty regarding my condition.
Experiencing Occasional Hematuria: Seeking Guidance
Greetings, medical professionals. I appreciate your assistance with the following situation. **Patient Overview:** - **Age:** 47 - **Gender:** Male - **Height:** 6 feet - **Weight:** 202 pounds **Symptoms Overview:** Approximately three months ago, I began to observe small traces of blood in my urine. It's a minimal amount, usually just a couple of drops occurring at the end of urination. I do not suffer from any pain, fever, chills, or urinary difficulties. Initially, I suspected that this could be linked to kidney stones or exercise-induced hematuria, as I maintain a rigorous exercise routine spanning two hours daily, seven days a week. My workouts alternate between strength training 3-4 times a week and cardio exercises, including rowing, treadmill use, the elliptical, stair climbing, and jump rope. After several weeks, I also observed tiny tissue-like fragments in my urine, prompting me to consult a doctor, as I suspected a urinary tract infection. Although I have an enlarged prostate, my physician considered it a benign issue, attributing the swelling to the potential chain reaction of a UTI leading to bladder infection and subsequently causing prostate inflammation. **Diagnostic Tests and Outcomes:** I underwent a comprehensive metabolic panel, which included tests for glucose, BUN, creatinine, and various electrolytes. All results fell within normal ranges, with the exception of a low BUN/creatinine ratio (8). Additionally, I received a Creatine Kinase (CPK) test, which returned normal results. A complete blood count (CBC) with differential was conducted, showing all parameters, including WBC, RBC, and hemoglobin, to be normal. Urinalysis reflected negative findings for GLU, BLO, NIT, and LEU. However, it indicated a small amount of bilirubin, a ketone level of 15, a specific gravity of 1.025, a pH of 5.5, and a protein level at 30. Uric acid levels were 8.1, within normal limits, though an inflammatory marker was mildly elevated. A sedimentation rate (Westergren) displayed a slight elevation at 19 (normal range is up to 15). A CT scan of the abdomen and pelvis with contrast yielded several findings: - **Lung Bases:** A few small pulmonary micronodules were noted, but otherwise clear. - **Liver, Spleen, and Pancreas:** All appeared normal without lesions. - **Kidneys:** Normal with no stones or masses. - **GI Tract:** The stomach was mildly distended, but otherwise normal with stool presence noted in the colon. - **Pelvis and Vascular Structures:** Solid organs and vessels appeared normal. - **Other Findings:** Prominent inguinal lymph nodes were potentially reactive, alongside a small left inguinal hernia. **Follow-Up Treatment:** Following these evaluations, my physician prescribed sulfamethoxazole for a duration of 28 days. I adhered to the regimen fully, and while undergoing treatment, all symptoms subsided completely. However, this occurred about a month ago, concluding in late December. **Current Situation:** This evening, after my workout, I noticed the return of blood traces in my urine. While I do not experience pain, I have difficulty with bowel movements, feeling persistently constipated regardless of food intake. This change coincided with a mild tearing sensation during exercise on the adductor machine. Additionally, I have developed a reddish rash on both arms, which had resolved during the antibiotic treatment but has now reappeared. Previously, this rash was effectively treated with prednisone, leaving me unsure if this is connected to my earlier symptoms. **Concerns:** I worry that standard medical tests might overlook a significant issue affecting my prostate, colon, or urinary system. My insurance policy does not cover colonoscopy or prostate evaluation, and I have been advised to consider these procedures, though they would cost nearly $7,000 out of pocket. While I understand the necessity of these assessments if needed, I prefer to seek a second opinion before committing to such expenses. It's important to note that there is a family history of cancer, primarily lung cancer. I welcome any advice or insight into my case and will provide any additional details you may require.
Gene Testing Outcomes Suggest Elevated Risk for MPN
A 27-year-old male of Irish heritage recently conducted a commercial gene analysis, and here are the findings: - **Rs12340895 (C;G)** Result Interpretation: "Doubles the likelihood of developing V617F-positive MPN." - **Rs3780374 (A;G)** Result Interpretation: "Significantly raises the probability of V617F-positive MPN manifestation." Based on my research, it appears that having these two genetic markers indicates a strong predisposition to this particular form of cancer. What steps should I consider taking to either prepare for or potentially postpone the onset of this condition? Should I discuss these findings with my healthcare provider? My studies suggest there isn’t a definitive cure for this condition.
Understanding Preseptal Cellulitis in Children
Hello everyone. I'm reaching out for assistance. My 6-year-old son recently experienced a concerning issue. He woke up on Friday with significant swelling around his eye, nearly closing it entirely. We quickly took him to the emergency room, where doctors diagnosed him with preseptal cellulitis. They prescribed antibiotics, specifically cephalosporin, as part of his treatment. However, after approximately 30 hours on the medication, I’ve noticed that his condition seems to have deteriorated. We’ve been applying warm compresses, which help reduce some swelling temporarily, but he now has a noticeable bump right in the center of the affected area. This morning, he woke up again with his eye completely shut. I’m uncertain whether I should return to the ER for further evaluation. I appreciate any advice or insights you can provide. Thank you!
14-Year-Old Male with Cough and Rash Symptoms
My 14-year-old son, who stands at 5 feet 3 inches tall and weighs 149 pounds, has been experiencing persistent cough and cold-like symptoms for slightly over a week. He stayed home from school on January 30 and February 3 as he was feeling unwell, but aside from that, he has managed to attend school. The predominant issue has been his cough. Initially, he had a runny nose for a couple of days, but that symptom has since resolved. He has not complained about a sore throat or experienced any fever. This afternoon, he reported developing a rash with red spots. He mentioned that it itches a little, but it's not uncomfortable, and he does not feel any pain. The rash is primarily located on his abdomen and chest, with some patches on his legs and a little on his arms, but there are no spots on his back. I checked his temperature, which was recorded at 99.4°F. He is fully vaccinated according to the standard vaccination schedule recommended by pediatricians in the United States. Our residence is near Vancouver, WA, in case that information is pertinent. Additionally, we have not changed any laundry or personal care products recently. What could this condition possibly indicate?
