I was diagnosed with a severe kidney infection and treated twice with anti botics. The last antbiotic was so hard on my system it left me with joint aches and retaining water. I just don't know, I still feel horrible it has been March 1, 2007, The drug was Levaquin and the docs are saying maybe the drug is still in my system? I am taking a water pill to allivate some of the swelling, my kidney still hurts... has anyone ever had anything like this happen to them?:confused:
