Hi, Tinnitus after getting flu indicates that the inflammation has spread to the inner ear structures. Inflammation of cochlea and the nerve gives tinnitus. Inflammation of vestibule gives giddiness also. Hence the treatment needed is as follows, preferably after getting examined by an ENT Surgeon as you need a valid prescription for some of the medicines. - Strict bed rest - Plenty of oral fluids - Steroids help a lot but need a valid prescription - Continue antihistamines if cold is still present - Anti-inflammatory as would be advised Sometimes it takes time for recovery as the inflammation is in a closed-cavity. Continue treatment till fully recovered. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, General Surgeon
