I started taking Levaquin for a sinus infection, a 10 day dose. I started noticing after a few days that I was irritable,depressed, aching and swelling from my wrist up to my elbow. After finishing my dose, the swelling went down. I am still having the pain. I have pain in my left shoulder, the cap of my shoulder. I have trouble sleeping because the pain gets extreme. I have pain in my right leg. The pain is on the back, the lower part--the achille tendon. I have trouble walking at times. The pain can be mild to severe at times. I even have the pain at night in bed. I didn't know what was wrong with me until a friend told me that these are some of the side effects of the medicine. If I had known, I would have never taken it. I feel like it is a struggle trying to get ready to go to work. I have yelled out loud at work because it would be so severe.
I quote from your message:
"...I have pain in my right leg. The pain is on the back, the lower part--the achille tendon..."
This is a known side-effect.
Please visit www.fqresearch.org - a fantastic informative site with lots of patient stories and information about side effects. The same can be said about www.fqvictims.org.
Google "floxies" and "floxed".
