I was coughing after being treated for cold/flu. So i visited the ENT. He prescribed me medicines for two times which included antibiotics, anti acid medicines and others. The 2 week-long course is about to be over today. But ever since the first treatment i am having tinnitus in the left ear which hasn't stopped at all. The doctor checked the left ear with a probe and said there's no issue till the ear drum and i will have to do other tests to check the reason for tinnitus. What test or treatment should be done now?
