I know many of you say cause "unknown" and perhaps this class of abx drugs has been discussed already -- I didn't go far back to try to find out.

Fluoroquinolones and Peripheral Neuropathy - David Perlmutter M.D.

My friend has a youngish male friend who is dealing with a lot of tendon damage and neuropathy from 22 days of this class of abx drug, which one I don't know, doesn't matter, they all do the damage. He took it for UTI.

My friend was also given this drug recently for UTI and she gook 2 tabs and quit, was already getting advanced pain issues.

This is a pretty damaging class of abx drugs and it's terrible they are still prescribed as often as they are.
