Went to my doctor on the 21st and she thought that I had a sinus infection and bronchitis and fluid in both my ear, she gave me a z pack inhaler and promet/ and codine. The next 2 days I developed a stabbing sharp pain under my left breast, the pain has been getting more and more intense. Went to the er yesterday and was told I have bronchitis and probably a muscle strain and basically that she didn't know why, while I was there she tried narcotics and Valium and nothing working. She sent me in the same condition I arrived in and prescribed me Valium. The pain is still unbearable. What should I do? I do get pneumonia every year around this time, the last time the doctor did not find it on the xray, but did on the CT scan.
