Avelox and support group

I was prescribed Avelox after an ongoing sinius infection. I took 3 doses of the 14 day prescription. After the 2nd dose I started having extreme muscle & joint pain from my neck to my toes. I had a slight rash on my forarms and around my knee joints and I had itching on my feet that felt like biting flies. I was unable to move without pain for 3 days after that. My doctor prescribed Medrol dose pack steriods to help with the joint pain. After the first day of the steriods the itching on my feet worsend to extreme burning itching to the point I lost my mind with no sleep and overdosed on benadryl. I slept that off and continued to have muscle pain/joint pain. I started researching on the web and found that this class of drugs can be very toxic to the body. I found a support group online and they gave me some advise to help with the pain. As of this day it's been 8 days since the first dose and I would say the pain is 90% gone (thank God)
