HI,
Welcome to healthcaremagic.com
I have read your query in detail and do understand your concern.
An itchy
rash on the lower abdomen can be due to a
fungal infection.
Remember to wear loose cotton clothing specially when at home.
Avoid hot humid climate, keep the affected area dry and avoid synthetic innerwear.
Do not use any over-the-counter medication over this area as it may be containing certain ingredients which may the increase the problem.
A course of oral and
topical antifungal medicine eg,
terbinafine is usually enough to cure one of this disease.
Are any other family members affected?
You may send a picture of the affected area for better assessment, whether it is herpetic or fungal.
However, you can continue to apply
neosporin over this until any other diagnosis is confirmed.
Hope this helps!
You can revert back if you have any other question.
Good luck!
