I had bronchitis, beginnings of pneumonia so the Dr. gave me seven samples ov Avelox. Around day 4 I woke up and my left heel was in enormous pain. I could not put weight on it and I have been hobbling around for a week. If you pressed on the outside part of my heel near the achiles tendon it would send sharp pain through my foot. I believe it was a direct result of avelox because I had done no strenuous activity. All I had done was sleep and lay in bed trying to get better. Then I wake up and have this to deal with. I will not ever take this drug again.
