Crotch Rash

[Thatguy29]

So for the past week I've had a rash on the left side of my groin area where my crotch meets my thigh. Its itchy but it doesn't burn. It almost looks like a big long red blister right there and I have little red bumps all by it. It's starting to spread onto the other side and I want it to stop. I've started using cortisone but it's not helping that much. Any ideas? I don't think it's fungal but I could be wrong.

Hello,
It can be due to tinea cruris which is a fungal infection of the groin. Treatment consists of topical antifungal cream which may contain miconazole, tolnaftate, terbinafine,ketaconazole and clotrimazole. Restrict wearing any undergarments at night and as far as possible keep the area dry.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

It could be jock itch which is fungal.  Look up information about it and let me know if that matches what you're experiencing.  If so, you can use an antifungal for jock itch.  To prevent this a good (and cheap) solution is corn starch.
