Hello sashi and welcome to Health care magic,
I am Dr Sriram Nathan , an ENT surgeon and I will try to help you out with your problem.
By your complaints it is understood that you have a hole in your ear drum and thats why you have pus discharge though it can be confirmed only by ENT examination.
If the hole and discharge is beyond three months then it is very unlikely to heal by itself. You need to take the complete course of antibiotic and also listen to the ENT doctors instructions such as keeping the ear clean and dry and not allowing any water to enter the ear to ensure that the ear hole heals.
A wait and watch period of three months is usual as i mentioned earlier so till then you need to wait. Take also a course of anti
histamine like levocetrizine in consultation with your doctor.
If the hole does not heal then you can go for a simple surgery called the
tympanoplasty and close the hole. Before that you need to get a full audiological evaluation such as audimetry, CT of the
temporal bone and get back to me or any ENT with the reports.
take care and get well soon
Dr Sriram Nathan
