Redness Under Fingernails After Sexual Activity
I've recently observed that three and a half fingernails on my left hand have developed some redness beneath the nail—there's a noticeable reddish tint at the tips and a lighter shade near the base. Additionally, the affected nails appear somewhat dry and exhibit a very slight yellowish tint at the tips on two of the fingers. As noted in the title, my left hand was quite active in recent intimate activities over the past week. I tend to prefer keeping my hands warm, although I have experienced some itching in the past couple of days that may be unrelated. My primary concern is whether this could be indicative of a fungal infection, especially since I've been experiencing some vaginal itching that started just a day or two ago. I've been with the same sexual partner for the last four years. As a side note, I think I might be overanalyzing the situation; I just want to rule out any serious issues. I haven’t changed any medications recently and I did visit the emergency department not long ago due to chest pain. The doctors suspected it might be related to allergies or stress. Thanks for your help! I’m a 28-year-old female. Duration: Uncertain, but I noticed it today. Medical history includes: Complex PTSD, night terrors, right bundle branch block, restless leg syndrome, insomnia, and seasonal allergies. Current medications: Venlafaxine 150 + 37.5 mg each morning, Bupropion 250 mg each morning, Trazodone 100 mg as needed for sleep, Gabapentin 400 mg as needed for restless leg syndrome and anxiety/nightmares.

It’s understandable to feel concerned about the redness and changes you’re noticing under your nails, especially with your recent intimate activities and the accompanying symptoms. While there could be several explanations for your symptoms, they aren't necessarily indicative of a serious problem. Let's explore this further.
Main Points:
You are experiencing redness and slight yellowing under your fingernails, along with some vaginal itching. This could relate to conditions like irritation, a fungal infection, allergies, or even stress. It’s good to rule out anything serious while taking care of your symptoms.
Explanation:
- Redness and Dryness Under Fingernails: This can occur due to several reasons: irritation from recent activity, an allergic reaction (which can also connect to your known allergies), or even a fungal nail infection.
- Slight Yellowing: This may indicate dryness or potentially a fungal issue, but it’s not uncommon for nails to show changes from environmental factors.
- Vaginal Itching: This can occur from a myriad of causes, including irritation from products, infections (like yeast infections), or allergies.
Next Steps:
-
Gentle Care:
- Keep your nails clean and dry. Avoid soaking them in water for prolonged periods.
- Apply a gentle moisturizer around the nails to combat dryness without irritating your skin further.
-
Monitor Symptoms:
- Keep an eye on the redness and dryness over the next few days. If it worsens, persists for more than a week, or if you develop new symptoms such as increased itching or discharge, it would be wise to consider further evaluation.
-
Consider Potential Irritants:
- Reflect on any new products or changes in routine that may have coincided with the onset of these symptoms. This includes soaps, hand sanitizers, or activities.
-
Stress Management:
- Since you mentioned a history of stress-related conditions, focusing on stress management techniques (like mindfulness or relaxation exercises) may help if there's a connection.
-
Watch for Other Symptoms:
- If you notice other symptoms like significant pain, swelling, or a change in the condition of your nails, it may indicate a more significant issue.
It’s great that you are being attentive to your body’s signals. Keeping track of your symptoms and any possible triggers can be very helpful. If your symptoms do not improve or you have further concerns, consider reaching out for more personalized healthcare advice. Stay calm and take it one step at a time!

Differentiating Between Histamine Reaction and Cellulitis
Subject: Male Height: 5’4” Status: Non-smoker Current Medications: None On the 15th, I experienced a bee sting. Although it caused some pain and a minor swelling, I initially had no severe reaction. However, after two days, a significant red patch emerged on my skin, accompanied by intense itching. I attempted to relieve the discomfort with calamine lotion and hydrocortisone cream, but neither provided any relief. This morning, I visited a minute clinic where the physician diagnosed me with cellulitis. I was prescribed a ten-day regimen of Cephalexin and a topical anti-itch medication, Triamcinolone, but the itching persists. I am skeptical about the cellulitis diagnosis since the itching is still quite severe. I haven’t experienced any fever or flu-like symptoms, and the redness has begun to fade since this morning. Would it be advisable to also take Benadryl?
Concern Over Dad's Bug Bite Reaction
Recently, my father, who is 63, scratched a bug bite on his leg, and I’ve noticed that the area has become swollen, inflamed, and painful. This incident occurred during nighttime, and he isn’t certain if the bite was from a tick. I’m wondering if the redness resembles the symptoms associated with Lyme disease or if it could indicate something that requires medical attention.
Identifying the Cause: Athlete's Foot or Allergic Reaction?
Age: 35, Male Ethnicity: Asian Residence: Bay Area Weight: 125 lbs For the past month, I've been experiencing an issue. Initially, I noticed tiny red spots that were quite itchy. I tried using a topical cream over several weeks, but instead of improving, the lesions expanded and appeared even more unusual. The treatment didn’t seem effective. Could this be a case of hives, as I suffer from them annually, or is it a fungal infection?
Concern About Possible Cold Sore
Greetings, I'm a 19-year-old female experiencing some anxiety over what seems to be a cold sore. Today, I discovered a tiny group of white bumps near the edge of my upper lip. They are accompanied by a tingling or numb sensation, making it difficult for me to determine whether this is simply due to dry lips or indeed an indication of a cold sore. If this indeed points to a cold sore, what steps should I take? I consider myself quite young and have never engaged in sexual activity; I’ve only kissed two individuals back in eighth grade. I'm perplexed about how I could be facing this issue now.
Identifying a Skin Condition: Eczema or Fungal Infection?
I’m a 20-year-old female, weighing 112 pounds and standing at 5 feet 4 inches, residing in California. I have a long history of dealing with eczema, but the current flare-up appears different from what I usually experience. The topical steroids prescribed for eczema have not been effective this time around. Although I have been applying clotrimazole cream, its results have been partial; I suspect it lacks the required potency. I previously attempted to use terbinafine but discovered that I have a severe allergy to it, preventing me from using that treatment. Does my condition appear to be fungal or is it still eczema? If it is indeed a fungal issue, I would appreciate recommendations for alternative treatments that could aid in my recovery.
