Hi shyeahmed ! May be this is fungal infection
. That you spreading by scratching one place then other. Now what to do! Take anti allergy
pill and fluconazole
tab once in a day. Apply fungal cream just apply don't rub and scratch. Now after doing every thing situation remain same, then go for pathological microscopic examination of that part of skin to know the cause. It will clear all doubt. Take care. Just try not to scratch , it spreads. Bye.
