Welcome in H.C.M.
I have gone through your query regarding your disease involving your ear , though you were having upper respiratory tract
I would like to say some times upper respiratory tract infection reaches to ear via Eustachian tube (tubular connection between ear and throat ) and give rise to fullness in ear followed by earache and discharge. Your case is also having the same pattern.
My opinion is that you should take antibiotic along with anti inflammatory and decongestant to get relief, if this much remains ineffective than thorough examination by ENT doctor will be necessary for further treatment.
