Thanks for writing to H.C.M. for query.
I have gone through your query regarding ear pain
and itching and on cleaning black wet cotton like discharge came out. Your all these symptoms favours to fungal infection
To treat this type of infection we should do-
(a) Keep ear clean and dry.
(b) Any broad spectrum antibiotic to be taken orally.
(c) Anti inflammatory should be taken orally.
(d) Antifungal ear drop
locally to be instilled in ear.
Hope this treatment will help you.
