hi dear ya these are related according to me, what i find from ur history is that it is some fungal infection
. these infections can be sometime subtle with minimal symptoms.
here are my suggestion.
use oint clodid b once a day for 7 days
this to be followed by oint clotrimazole
1% twice daiy for one month.
u ll start getting relief within a week but u must continue entire treatment
if u dont get relief in a week visit a dermatologist
