Welcome in H.C.M.
I have gone through your query regarding discharge from your ear , due to perforated ear drumm and infection.
Your clinical history suggests that you are suffering from chronic suppurative otitis media
. To manage it you are advice for these investigations-
1- C.T.Scan of ear.
2- Culture and sensitivity or ear pus.
3- Pure tone audiometry
4- Blood- CBE, ESR
, blood sugar (F & PP)
Consultation with ENT doctor is must for examination and treatment to avoid further complications.
