Age 52, was diagnosed with my first right ear infection one week ago. (after having the flu , the previous week) Was put on amoxicillan 875mg 2 times daily. Ok, my ear is totally plugged, no pain, but when I shake my head, I feel like I have water juggling inside. How long does this last. I do have some sinus pressure on the same side, so I have been taking an decongestant this week also. The plugged up/no hearing is what is really bothering me. Any suggestions to relieve my plugged ear?
