After numerous tests including
blood work, ekg, chest X-rays and urine tests, they determined I had a bad UTI. All my other tests came back normal. I took the percription until it was gone, but I continued to have a day every 4 days or so where I couldn't take a deep breath. On Monday, I went to the doctor because I couldn't take deep breaths. After running routine physical exam, the doctor determined that my shortness of breath was do to acid relux. She started me on ranitidine.
