I had a Prostate Infection that Bactrim and Doxycyline would not cure. So the doctor said the only thing that would cure i is Cipro or Levaquin. I was on it for a month. I tuffed it out and I had to take Tramadol to kill the leg pain. One day I accidentally took an extra Cipro pill and within a half hour, I had a hard time walking. I actually could feel my achilles heel pulling when I walked like it had shrunk. I've been off it two months now and I don't feel any better. I am tired and aching all the time. I have no strength. My back and knees hurt everyday to where I can't function without taking some kind of pain medicine. How long does this last? I talked to a lawyer who is doing the Cipro lawsuits and he said unless I had a ruptured tendon or can get a doctor to say I have chronic tendinitis, I have no case. I have never felt so bad in my life.
