My husband has mastoiditis and otitis media with effusion also called glue ear.Did you mean otitis externa or eczema? He has never had the I.V of antibiotics just the pills. He has had tubes put in his ears and they vacuumed out the fluid when they put them in. They also wanted to do mastoidectomy surgery where they go in and scrape the infection out of the bone but he didn't want that intrusion in his head. Do you have tube in your ears? To cope he exercises, stretches and does relaxation techniques. He also eats well, nutritious foods. Limiting caffeine will reduce the fluid/mucous that the body makes. It can be an ongoing situation but it can be managed. I should think that the pain will subside when the infection clears up. Limiting CT scans for now is probably a good idea unless there are further complications or it doesn't clear up. I wish you the best in your recovery. Keep us posted on your progress.
