Unexpected Blistering Episodes
I've been dealing with unexpected blistering episodes. About half a year ago, I awoke to find a large blister measuring approximately 3 cm by 3 cm on my leg, accompanied by a smaller one of about 1 cm by 1 cm on my foot. Both eventually ruptured, leading the larger blister to transform into a sloughy sore that took three months to properly heal, leaving behind a noticeable scar. Today, I experienced a similar occurrence, waking up to find a blister on my left knee. It is quite painful but does not have an itchy sensation, and it doesn’t resemble a typical bite at first glance. There’s some redness surrounding the blister, but it doesn’t seem to be spreading. I’m a 33-year-old female without any medications or significant past medical history. There is a family history of hemochromatosis and Type 2 diabetes. Has anyone encountered anything like this before?

It sounds concerning to experience these unexpected blistering episodes, especially since you’ve had a similar issue in the past. Blisters can arise from various causes, and while some could be minor, others may indicate an underlying condition that needs attention. Let’s break this down.
Main Points
- Blister Formation: The blisters you are experiencing may have various causes, including skin conditions, autoimmune issues, or reactions to substances.
- Monitoring Symptoms: It’s crucial to observe any changes in the blisters and associated symptoms to understand their nature better.
Explanation
Blisters can result from friction, burns, allergic reactions, or skin conditions like autoimmune diseases. Given your family history of hemochromatosis and diabetes, those might be factors to consider, but they don't directly indicate the cause of your blisters. Painful blisters, especially if they are recurrent and slow to heal, can sometimes relate to autoimmune conditions or infections.
Next Steps
- Monitor the Blister: Keep an eye on the new blister on your knee. Note any changes in size, color, or the presence of pus or worsening redness.
- Avoid Irritation: Try to keep the area clean and covered with a sterile bandage to prevent infection, and avoid popping the blister.
- Document Symptoms: Write down details about each blister episode, including any triggers you notice, locations on your body, and accompanying symptoms like fever or fatigue.
- Consider Skin Care Products: Use mild, unscented soap and moisturizing lotion on your skin to reduce irritation.
- Caution on Family History: Given your family history, consider lifestyle factors that can help reduce your risk of diabetes, such as maintaining a balanced diet and regular physical activity.
If your symptoms worsen, or if you notice other systemic symptoms, it’s important to seek professional advice for a thorough evaluation. Remember, it’s always better to be proactive, especially with recurrent issues like this. Let me know if you need more information or support!

Understanding Occasional Memory Gaps
As a 41-year-old mother, I've been dealing with sporadic memory lapses for a number of years. My journey into motherhood began six years ago, and honestly, I can’t clearly recall if I experienced such issues before becoming a parent. Currently, I have two children, with the youngest being three years old. There are instances where I completely forget fundamental details—whether they relate to the world around me or my own life. Just the other day at work, I found myself unable to visualize my home; I couldn’t remember its color, shape, or location for about ten seconds. Thankfully, that memory returned swiftly, but the initial surge of anxiety and confusion over not recalling such crucial aspects of my life was unsettling. Occasionally, I also catch myself forgetting the current year or even the month, although these small incidents happen infrequently—perhaps three times a year at most. While I am certainly under stress and experiencing sleep deprivation, I assume those feelings are quite common among working parents. Regarding my health background and medications, I deal with migraines, which I manage through Botox, steroids, and preventive medications like Ajovy, as well as Nurtec for pain relief when necessary. In addition, I have been grappling with anxiety and depression and recently began taking duloxetine HCL. I started with a 30 mg dose last week, planning to increase it to 60 mg later this week. I appreciate any guidance you can provide. The thought that these memory issues could signal the onset of early dementia frightens me, especially since my grandmother suffers from dementia, but she is in her nineties, and my mother, who is in her seventies, shows no signs of it.
Swelling Behind Ear - Insights Needed
Hello everyone, I’m a 25-year-old female and discovered a sensitive, movable swelling located at the back of my ear this morning, specifically on the rounded area situated just above the mole where my ear connects to my head. Does anyone have any thoughts on what this might be? Could it be related to lymph nodes or is it just an acne bump? I’ve been quite anxious about lymph node issues lately and have been pressing down on my jaw and the area behind my ear frequently. I’m curious if this could be connected. Dealing with health anxiety can be exhausting. I have an appointment with a doctor on Wednesday.
Questions Regarding COVID Antigen Test Results
I’m a 30-year-old male, standing 6 feet 1 inch tall and weighing 230 pounds, of Caucasian descent. I spent Saturday evening with my parents, but by Sunday afternoon, both were feeling unwell and subsequently tested positive for COVID-19. My wife and I care for an elderly gentleman who's 88, so we decided to acquire some COVID-19 Antigen Home Tests. Though both of us had been experiencing diarrhea, I am uncertain if it has any connection to COVID, especially so soon after possible exposure. I understand that antigen tests often lack reliability within the first 2 to 5 days post-exposure, but for precaution's sake, we both decided to take a test on Sunday night. After waiting the recommended 30 minutes, our results returned negative. However, upon examining my test again two hours later, I noticed a faint line that suggested a potential positive result, while my wife's test did not indicate anything unusual. I am aware that results beyond the initial 30-minute window are generally not considered valid, particularly just one day after a potential exposure. I've come across information that suggests a faint positive which emerges after a couple of hours may indicate the presence of the virus, albeit in insufficient quantities to pose a contagious threat or raise significant concern. This morning (Monday), I noticed I have developed a sore throat, which might be attributed to dehydration, and some muscle aches, possibly a result of my workout at the gym on Saturday. While I’m not overly worried about my own health, I am concerned for the elderly gentleman we care for. What are the chances that the delayed faint positive line implies I may have contracted the virus, and when would be an appropriate time to conduct a follow-up test?
Understanding PET Scan Findings
Hello! Here’s a brief overview of my situation. I have a background of sarcoidosis, which has been in remission for nearly a year without treatment. Recent blood tests indicated heightened inflammatory markers, particularly a sedimentation rate of 80. My physician suggested a PET scan as both the CT scan and MRI did not reveal any signs of sarcoidosis. I am seeking some assistance in understanding these results, as I am feeling quite anxious about them, especially since my next rheumatologist appointment is not scheduled until the end of the month. **Findings Summary** 1. There is a notable increase in metabolic activity in the posterior nasopharynx, potentially indicating mild soft tissue prominence, which might be the result of lymphoid hyperplasia, mucosal activation, or an inflammatory process. It is advisable to conduct short-term follow-up with PET-CT in three months to monitor any changes. 2. Bilateral cervical lymph nodes show small sizes with mild to moderate increased metabolic activity, likely due to reactive or inflammatory causes. 3. There is no indication of metabolically active malignant or metastatic disease, nor is there any evidence of active lymph node disease. **EXAM: Whole Body PET/CT** **CLINICAL HISTORY:** Previous diagnosis of sarcoidosis **COMPARISON:** CT Chest with Contrast, dated 2025-06-05 13:08:13 **FINDINGS:** - **Metabolic Activity Reference Points:** 1. Mediastinal blood pool SUV max at 2.3 2. Liver SUV max showing normal levels at 3.2 - **Head and Neck:** Notable hypermetabolic activity in the posterior nasopharynx, measuring around 0.7 x 1.8 cm with a max SUV of 6.6. There are small bilateral cervical lymph nodes, the right one measuring approximately 0.7 x 1.3 cm with a max SUV of 3.2. Increased metabolic activity is seen symmetrically around the base of the tongue and tonsillar areas, likely indicative of lymphoid hyperplasia or normal mucosal activation. - **Thorax:** No significant hypermetabolic foci noted. - **Abdomen and Pelvis:** No notable hypermetabolic foci present, although increased uptake in the endometrial cavity suggests changes related to hormonal activity associated with the menstrual cycle. - **Lower Extremities:** No significant hypermetabolic findings. - **Bone:** There are areas of asymmetric increased uptake within the axial and appendicular bone marrow, likely representing marrow hyperplasia or activation.
The Impact of PDE-5 Inhibitors and Beetroot Juice on Hearing
A user reported experiencing tinnitus after occasionally using sildenafil, a PDE-5 inhibitor, raising questions about the potential effects of beetroot juice on hearing health. Although this inquiry may seem somewhat broad, it seeks to understand whether beetroot juice might also be ototoxic, or conversely, if it is indeed safe and why that is the case. From what I gather, both sildenafil and beetroot juice have the capacity to boost nitric oxide levels, which in turn can enhance blood circulation. It's known that the cochlea is especially sensitive to variations in blood flow, potentially leading to harm. PDE-5 inhibitors are frequently discussed in relation to ototoxicity, yet sources on the internet generally indicate that beetroot juice does not possess ototoxic properties. Could there be other factors at play, or might beetroot juice and other natural nitric oxide boosters actually be ototoxic as well? I am trying to determine whether beetroot juice represents a safer—albeit less potent—alternative to conventional PDE-5 inhibitors.
