Welcome in H.C.M.
I have gone through your query regarding recurrent pain in ear, and every time on flushing
whitish material comes out and gets relief in pain.
Your history of illness favors that you are most likely having fungal infection
in ear. to treat it and prevent further attack you should do-
1- Never use mustered oil ear
2- Keep ear clean and dry.
3- Put an ear drop
having antibiotic + anti fungal and steroids
I hope this will help you.
