i took avelox (same family of drug as cipro) 8 months ago and ive been confined to a wheelchair ever since. tore several tendons wdespread muscle, joint pain, phototoxicity/sjs, vasculitis, nerve damage, numbness, paranoia other cognitive problems , the lsit goes on an on. my life has been completely destroyed im in pain continuously. cipro is not just an ordinary antibiotic it works like a chemotherapeuic drug does ataking cells. hat kind of antibiotic changes apersons dna. one of the most dangerous drugs on the market. do some research and you will see that hundreds of thousands of people have had their life altered from this poison. the popping and twitching are common side effects to cipro and other fluoroquinolone drugs. adverse reactions can occur months later so its hard to trace back to the drug. whatever the cause i wish you the best.
