Thanks for your query.
You have applied clotrimazole
for upto 3 weeks.
Continuous usage of an antifungal would have surely resulted in either complete healing or atleast improvement in the ringworm infection till now.
You seem to have either developed an eczematous skin condition or an infective condition.
Treatment of the same varies from the use of topical steroids
or using topical antibiotic
I would recommend that you should see a local dermatologist
for the same.
You can also send me pictures and ask me a direct query on this forum.
Hope it helps,
Dr Geetika Paul
