Hi there. I am a 40 yr old female, good health, former smoker. I doctored a cold at home for almost 3 weeks, went to Urgent Care last Sunday morning & was prescribed a Zpack. On Wednesday night, after dinner I started to lose the hearing in my right ear. Within 30 minutes, my hearing in that ear was gone. I put a couple of drops of vinegar in it, let it drain, then held a hot wash cloth on it, didn t help. I was soon in excruciating pain & went to the ER. The pain was so intense, that I was given a shot of dilated. I was diagnosed with a sever ear infection & sinusitis & prescribed Amoxicillian & (OTC) Sudafed. I am on day 5 of those with still no relief from the cold & no hearing in my right ear. What could possibly be wrong?
