I coughed for 3 months, sometimes I coughed so hard that I would throw up it was an awful feeling, my body ached all the time, even the bottom of my feet , It hurt so bad to try and turn over at night, I had terrible headaches my symptons were very much like chronic sinusitis andI just slowed down because I didn't feel good. I've been off this medicine for 2 months and I'm feeling better but it does make me painful in the area of my kidneys on the left side and I have blood in my urine which is also a side effect and I did have an ultrasound today, I truly believe that this medicine almost killed me.
