Circular, red rash on right side of rib cage, itching, gets bigger on scratching. Causes?
Patient: Hello, few months back i had a small circular red what looked like a rash on my right side on my ribcage..it would itch ..the more i scratched it it became bigger ...then it went away ....and then i noticed a dime size dark rash under my armpit ....that also itches ..and the more i scratch the more it gets bigger ....what is this? Doctor: hi,the skin rash that you have is tinea corporis. armpits and groins are the commonest areas for this fungal infection. you need to apply topical antifungal cream twice a day for around 10-15 days. you can also take antiallergic tablets if there is lot of itching.the armpit area should be kept dry. wear loose cotton clothing to prevent moisture retention in the body folds.                       feel free to contact for further queries.
