Could This Be Ringworm?
For over a month now, I've had a rash on my left thumb, specifically the F32 area. I first observed it when it was roughly the diameter of a pencil eraser. Interestingly, I just resumed taking Zoloft and Wellbutrin about a week ago; however, the rash had already made its appearance prior to starting these medications.

It sounds like you're dealing with a persistent rash on your thumb, and I understand that it can be concerning, especially when paired with recent medication changes. The characteristics you describe, including a round shape and possibly itching, could suggest ringworm, a fungal infection. However, other conditions like eczema, psoriasis, or contact dermatitis could also be possibilities.
Explanation
Ringworm is commonly identified by its circular, red, raised edges and often has a clearer center. It usually thrives in warm, moist areas of the body. Given that your rash has been present for over a month, it’s important to monitor its progression and how it responds to any treatment you try.
Next Steps
-
Symptom Diary: Keep track of the rash’s appearance, any changes in size or color, and whether you experience itching or discomfort. This information will be helpful for further evaluation if needed.
-
Over-the-Counter Treatment: Consider using a topical antifungal cream, such as clotrimazole or miconazole, which is available at pharmacies. Apply it according to the package instructions, usually twice daily, for at least 2-4 weeks, even if symptoms seem to improve sooner.
-
Keep the Area Clean and Dry: Ensure the rash area is clean and dry. Avoid covering it tightly with bandages that may trap moisture, as this can worsen fungal infections.
-
Observe for Changes: If the rash does not improve after a few weeks of self-treatment, starts spreading, or if you develop other symptoms (like pain or fever), reevaluate the situation more seriously.
Remember that while many skin conditions are manageable at home, professional evaluation may still be necessary for accurate diagnosis and treatment, particularly if symptoms persist. Please let me know if you have any more questions or need further assistance!

Resources for Safe Mouse Cleanup
While it may not be a typical inquiry for a healthcare professional, I find myself in need of guidance. Recently, we had an uninvited mouse visitor in our home, and unfortunately, it left droppings in my children's toy storage and on the changing table. I am seeking advice on how to effectively disinfect all affected items or determine if disposal is necessary to prevent any health risks. My children are quite young, at 2.5 years and just 4 months old. If they’ve potentially been exposed to mouse droppings, should I reach out to their pediatrician? For reference, I’m a 32-year-old female, standing at 5'6" and weighing 140 pounds, not currently on any medications.
Excessive Electrical Shocks Encountered
Hello everyone! This is my inaugural post here since I don't frequently use Reddit. I'm a 15-year-old male, and I've recently been experiencing an unusual frequency of electrical shocks. Whenever I come into contact with anything that is either highly charged or conductive, I receive a sharp, irritating jolt. This situation has become increasingly bothersome. For instance, I can only grasp my Mac charger by the cord and not the plug itself. I'm curious if anyone has insights into why this is happening. Please let me know; I hope it's nothing serious! 💕
Urinalysis Inquiry
Subject: Urinalysis Results Review Age: 23 Height: 5'2" Weight: 101 lbs Greetings! I would appreciate it if you could review my urinalysis findings. The test was conducted yesterday, just one day prior to the start of my menstrual cycle, and I am now currently on my period. Below are the details of my results, as I need this information to fulfill a prerequisite for my employment. Additionally, I would like to know whether my menstrual cycle may have influenced the outcome of the test. I typically experience frequent urination, yet I do not have any discomfort or pain while urinating.
Combining Ketorolac with Alcohol: Is It Safe?
Recently, I unknowingly mixed a 10mg dose of ketorolac with half a bottle of 4.5% beer. At that moment, I wasn't aware of the potential risks involved in this combination. It wasn't until I was partway through my drink that I thought to look it up. Now, I’m wondering if it’ll be fine for me to have a drink tomorrow night after stopping all ketorolac use, especially since this medication hasn’t been effective for my pain relief. To give you an idea of the timeline, I took ketorolac around 2 PM and didn’t start drinking until 11 PM.
Concerns About My Eye Condition
I'm a 19-year-old female, weighing 190 pounds and standing 5'5". Lately, I’ve noticed some troubling changes in my eyes. There are prominent, red veins extending from the inner corners of my eyes into the irises. Additionally, there are bright red streaks and pools forming at the lower part of both eyes beneath the eyelids, bordered by a yellowish hue. When I consulted two different doctors, they were unable to pinpoint the issue and simply recommended lubricating eye drops. Unfortunately, the condition seems to be deteriorating, with the redness spreading further. While there is no significant pain, keeping my eyes open feels like a struggle, and my vision has become increasingly blurry, leading to some headaches. I’ve been unwell recently, but I’m uncertain if this has any relevance to my eye problems. Any advice or insights would be immensely helpful.
