Hi,
Thank you for your query.
1. The ideal way to diagnose this is to get your ear examined by an
ENT Specialist and a Skin Specialist. Do you wear any ear-ring?
2. If the ear canal and
eardrum is normal, a
local antibiotic, anti-fungal and
steroid combination cream should work well. You may request an anti-inflammatory an ana anti-allergic medication to decrease the itch and hot sensation / occasional pain.
3. Check if the rash looks like clear vesicles. In such as case
Herpes Zoster infection must be ruled out as it requires aggressive treatment.
4. Hence I would urge you to seek immediate medical attention.
Regards.
