ibromyalgia
"I started taking Tramadol for undiagnosed knee pain about ten years ago.  It was a miracle.  I was actually able to walk for most of the day without pain.  I finally had knee surgery, so I only had to take it a couple times a week.  Then, I was diagnosed with Fibromyalgia 5 years ago and had brain surgery, which I have had many bad effects from.  The tramadol and also Percocet get me through my days.  I want to kiss whoever created the tramadol."
