sinusitis
"I was prescribed Levaquin 500mg 1x/day for chronic sinus infections.  On day 8 (of a 10 day prescription), I woke up feeling like I'd been hit by a truck.  Every tendon in my body hurt.  Even the tiny ones in my fingers.  It took me till the next day to realize it was the Levaquin causing this (no doctor or pharmacist had warned me).  I threw out the day 10 pill.  This was 3 mths ago.  For the first two weeks, the pain got worse.  I was unable to walk for a week.  After that, it gradually began to subside and I began to be able to walk, albeit very slowly, again.  I spent about a month on bed rest.  I just saw an ortho yesterday and she is optimistic about my progress.  She said it may take about 1 yr for me to heal.  I am about 85% better."
