### input:
I have what I believe to be a ringworm since the beginning of July. Its a circle but its huge...a little bigger then a silver dollar. It use to itch and was red...it is no longer red. I started using Lotrim beginning of August and its already September. It is very very dry but doesnt itch anymore....but I wanted to know when will the color come back? Its on my arm...a huuuuuge white circle...very noticeable. It actually is very dry OUTSIDE of the area as well (I think because I used the Lotrim in that area as well to be on the safe side). I just want my complection back =(. Also, (how embarrasing), how do you prevent getting pimples on your butt? I am pretty - 27 yrs old - but scared to be intimate because I get 3-4 new pimples everytime the other ones FINALLY disappear. It takes FOREVER FOR THEM TO HEAL when you mess with them (I JUST WANT A CLEAR REAR ! ! ! !) HEEEELLLPPP  please!

### output:

HiT hank you for asking ChatDoctorI have gone through your query. Your problem is most likely Fungal infection Tania corporal (ring worm). It is better to rule out that by showing a dermatologist. If you send a picture of it I can comment on it more. For such cases I advise ointments witChatDoctorbination of antifungal fluconazole, antibacterial gentamicin and corticosteroid clobetasol. Clotrimazole is resistant in some, but fluconazole is more effective. I also give fluconazole tab weekly once for oral intake to stop recurrence. Getting pimples on butt can be due to constant accumulation of sweat and dirt for long time. You should clean properly and use Chat Doctor. Using vitamin C also will be helpful in preventing such pimples on butt. Hope this may help you. Let me know if anything is not clear. Thanks.
