sinusitis
"Two years ago, my doctor gave me a five day dose of Levaquin for a bad sinus infection.  I have to admit, by the second day, all of my sinus symptoms were nearly gone.  However, after about two weeks, I started noticing that the tendons around my heal and arch of my feet started to hurt.  About a week later, the tendons in my neck and both elbows started hurting.  To this day I still have pains in my tendons that come and go.  The only thing that helps is NSAID's, stretching and B12 also seems to help.  "
