I have been on Levaquin now for almost 2 years. Yes that's right 2 years. I was perscribed it for treatment of a recurrent cellulitis secondary to a primary lymphedema.. I have been wondering why my hands hurt and I can hardly move my knees. I never knew that Levaquin had such side effects. My Doctor never told me about this. I have been in so much pain my physical activity level has dropped to near zero.
