Hi. As per your case history of onychomycosis, my treatment advice is - 1. Onychomycosis is fungal infection of nails. So your complain of skin infection is suggestive of paronychia. 2. Take a NSAID like ibuprofen for pain and levocetrizine for itching. 3. Apply an antifungal cream like clotrimazole cream twice daily on it. 4. Other treatment options are oral fluconazole, itraconazole and terbinafine taken only after consulting a dermatologist. Thanks. Dr. Harshit bhachech. MBBS, DDVL.
