Hi, Welcome to Health care magic forum.
It appears to be the allergic reaction
to the pads, or may be a fungal infection
I advise you to consult a dermatologist
for diagnosis and treatment.
I usually prescribe to my patient with such symptoms cifixime, grisofulvin, and topical mixed steroid
cream for local application.
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to hasten the recovery.
Wishing for a quick and complete recovery. Thank you.
