Levofloxacin
"After taking this drug for 5 days I had excruciating pain in my arms elbows hands fingers and knees. I have spent most of my nights awake waiting for these pain episodes to cease and sleep 1 more hour. I had one return visit to my doctor and one trip to urgent care because my hand a fingers were blue. Today is my 7th day off of that poison and I am beginning to be be almost pain free   Do not take it"
