Hi, I had a sinusitis infection 3 weeks ago, My right ear and nostril were blocked, I was prescribed boxyclav 625 for 5 days twice a day with steaming and Flunim. I started feeling better after 3 days ,but my right ear started ringing which has not stopped till now. I went to an ENT as well a week back. I am now using Flutiflo nasal spray ,steaming ,otrivin with allegra tab once a day. Though I feel the noise is very slowly reducing, I am running out of patience now.
