I was prescribed a 10 day dose of levaquin for my saliva gland being swollen. At first I had stomach problems with the drug. Upset stomach usually after taking the pill. Then after the 9th pill I started having severe muscle pain and then joint pain. I couldn't sleep at night for the joint and muscle pain. I had to stay on ibuprofen for the pain per the doctors orders for a few days for the pain. The pain was so severe that I couldn't walk up and down steps or move very good. I wouldn't ever take this again.
