Pennicillan symptoms and conditions

I was prescribed levaquin for for a respiratory infection. Instead of getting better I got worse. I was weak, began to have joint pain as well as the infection problems. I called my doctor after doing research on the internet. He told me to stop levaquin and to take advil. This didn't help. When I went back to him he tested me for lupus, ms, and RA. He eventually sent me to an arthritis specialist that I am still seeing 5 months later. Although she had never heard of these side effects until I explained them she has supported my concern that I have been suffering from an adverse reaction to the medication. I still suffer from joint pain and swelling as well as an acute burning pain in my thigh. The only treatment that I am receiving is steriod shots in my joints which do offer some relief. As I sit here tonight my leg is extremely painful. Will it ever go away or are we all doomed to suffer these ill effects the rest of our lives. I hurt... if anyone knows of a class action lawsuit please share the information.
