Understanding Foot Blisters: Possible Causes
I’m an 18-year-old female, standing at 4’11” and weighing 115 pounds. Currently, I’m not taking any medications and I smoke cannabis regularly. Throughout my life, I haven’t experienced any significant health issues, neither in the past nor now. However, today I noticed some blisters on my foot that suddenly appeared. After finishing my shift at work, I discovered that my sock had adhered closely to my skin. Upon removing it, I was surprised to find blisters underneath. It's worth mentioning that I tend to sweat excessively while working, often to the point that it seems like I’ve just stepped out of a shower. Although I walk a lot during my shifts, it didn’t bother me until I actually saw those blisters. They are quite itchy, accompanied by some blanching, but interestingly, they don't cause any actual pain. There's also one blister located near my ankle. This is my first experience with blisters, as I haven’t encountered them anywhere else before. Could this possibly be related to HSV, eczema, or perhaps heat rash?

It sounds like you’re dealing with foot blisters that formed after your shift, likely due to a combination of friction from your sock and excessive sweating. Let’s break down your situation and provide some actionable steps to help you find relief.
Main Points:
- The blisters may be due to friction and moisture, not necessarily related to herpes simplex virus (HSV), eczema, or heat rash.
- Itchy, non-painful blisters that form in this situation are usually caused by irritation rather than a serious condition.
Explanation:
Blisters often occur due to friction, which can happen when your skin rubs against your sock while you walk. Excessive sweating can exacerbate the issue by making your skin more prone to irritation and blister formation. The itchiness and blanching you describe are common with blisters and don’t indicate a severe problem.
Next Steps:
-
Keep the Area Clean: Wash the blistered area gently with soap and water. Pat it dry; avoid popping the blisters, as this can lead to infection.
-
Moisture Management: Change into dry socks and consider using moisture-wicking socks during work to reduce sweating. You might also consider foot powder to keep your feet dry.
-
Buffer the Blisters: If the blisters are in a place where they will get irritated, you can use a blister bandage or gauze to protect them. This is especially useful if you need to continue wearing shoes that might rub against them.
-
Monitor the Blisters: Keep an eye on the blisters for any signs of infection, such as increased redness, warmth, swelling, or oozing. If they change or worsen, it would be wise to consider further action.
-
Evaluate Footwear: Pay attention to the fit of your shoes. Ensure they’re not too tight and provide adequate support. Shoes with more room and cushioning can help prevent future blisters.
If the blisters persist or you experience any concerning symptoms, considering a healthcare consultation would be a wise decision. Please don’t hesitate to reach out if you have further questions or if there are changes in your symptoms!

Could This Be a Concussion?
At approximately 5:30 PM yesterday, I, a 21-year-old female, experienced a fall where I struck my head against the side of my bed. Almost immediately after, I began feeling extremely nauseous and developed a headache. This sense of nausea lingered for about three to four hours before subsiding, although the headache persisted until I eventually went to bed at 7 AM. Upon waking today, the headache had dissipated; however, I notice an unusual sensation in my head along with some mild discomfort. If I were to quantify the pain on a scale of 1 to 10, it would rate at around a 3. Could this indicate a concussion, or am I just worrying too much?
Swelling Around My Elbow: Seeking Insights
I am a 37-year-old male, a non-smoker, in good health without any ongoing medication. Recently, I've noticed a noticeable swelling on my elbow that has persisted for the past two days. The affected area is red, warm to the touch, and slightly painful. This issue appeared suddenly. Fortunately, I can move my elbow without discomfort and maintain a full range of motion. After visiting an urgent care facility last night, the medical staff suggested a possible diagnosis of either bursitis or an infection, prescribing doxycycline for treatment. While there has been a slight reduction in swelling since I saw the doctor, it remains quite pronounced today. In addition, I should mention that four days ago, I squeezed a small blemish on my elbow. I stay active and typically work out regularly: I did an arm workout five days ago, another one three days ago, and I ran five miles just two days ago. What could be causing this swelling and discomfort? Any insights would be appreciated!
Seeking Advice on a Persistent Rash
As a 24-year-old woman weighing approximately 101 pounds, I have been diagnosed with various mental health and neurological conditions, including depression, anxiety, insomnia, schizoaffective disorder, and epilepsy. My current medications include escitalopram, levetiracetam, Abilify Maintena, quetiapine, and cetirizine. Recently, I developed a body rash that was determined by doctors to be an allergic reaction to amoxicillin. This diagnosis seems puzzling, considering I have taken amoxicillin multiple times throughout my life without encountering any issues. Despite discontinuing the antibiotic several months ago—after only a brief period of use—my rash remains persistent and has worsened over time. It has now spread from my shoulders to my chest, back, and is even crawling up my neck. Unfortunately, the treatments I have tried, including a prescribed cream, have yielded no relief, and my pleas for assistance from medical professionals have gone unanswered. I would greatly appreciate any insights, suggestions, or guidance regarding this troublesome condition. Thank you for your help!
Concerns Regarding My Mother's Foot After a Fall
I'm feeling a bit anxious about my mother. To summarize the situation, she took a tumble on the street earlier today. At that moment, the only visible injury was a minor scrape on her elbow, and she was able to walk without discomfort. However, after about 5 to 6 hours at home, she has suddenly found it impossible to place any weight on her right foot. This unexpected delay in symptoms is worrying me. If it were a sprained ankle or a fracture, I would have anticipated her experiencing pain and difficulty moving immediately after the fall. Now, she's just wanting to rest, but I can't help but wonder if a visit to the emergency room or at least urgent care is necessary. Any advice or assistance would be greatly appreciated. Thank you!
Severe Discomfort in Left Ear during Flight
I am a 21-year-old male, standing at 181 cm and weighing 98 kg. Last week, during my descent from a flight while in Egypt, I experienced tremendous pain and a sensation of blockage in my left ear that persisted for several days. Approximately two days after that incident, I began to notice unpleasant burbling and movement sounds in my ear, which were quite painful. Luckily, my right ear remained unaffected. Now, with another flight scheduled for tomorrow, I'm looking for tips to prevent a recurrence of this issue. I have already tried using nasal sprays, anti-allergy sprays, and even earplugs designed for air travel. Any assistance you could provide would be greatly appreciated. By the way, I only smoke and use the listed nasal sprays and do not take any other medications.
