I took Levaquin in March of 2004, for a spider bite. I had a 5 day dose pack. After the 2nd pill, I started having nightmares (I usually never remember my dreams), but attributed them to the spider bite. By the time I finished the meds, I had swollen hands, almost fell over when I got out of bed one morning, as I have no sense of balance, was having nighttime chills, along with many other things. Three and 1/2 years later, I have had to make my rings bigger, and my muscle pain still exists. I believe it is getting worse. I have been tested for Lupus, RA, and other autoimmune diseases, all neg. I still have an abnormally low platelet count which stated shortly after the levaquin too. I am thinking of contacting a lawyer, as this drug needs to be taken off of the market.
