I was recently on Biaxin for Bronchial infection. I have never felt so bad in my life. I was taking a med to get better and began to feel worse. My Whole body was severely sore to the touch. It hurt to even be hugged. I felt upset all the time and extremely irritable. I honestly thought something was seriously wrong with me. I called the Dr. and she said to stop meds it was a side effect, and she told me to drink as much water as possible to flush meds out of system. Was told in 24 hours I should feel better. Horrible experience do not recommend Biaxin.
