Levaquin and alexander

I started taking Levaquin 500mg on 3/14/03 for a sinus infection. it is now 3/20/03 I have severe pain over my entire body . It started on 3/19 with pain in my arms and my forearms. My hands are involved and my elbows ,sholder,back ,neck, hips , legs,knees you name it, it hurts. I am so scared. Iam 34 years old and have two sons and I could not hold a fork to cut my sons sandwhich for lunch. I am worried that I will be pain for a long time. My doctor seems to know about the side effects. That scares me after reading these posted statements. please if any one out there can shed any light on this topic for me please let me know. Marylee Alexander Pennsylvania
