back pain
"My doctor switched me to Tramadol after Tylenol 3 started losing effectiveness. I was on Ty 3 for years, after four lumbar surgeries, two fusions, continued pain...  taking 3-4, 50 mg. Tramadol/day, trying to keep it at three. Not pain free, but at least bearable. Unless/until it wears off. 

I have joint pain, my elbows hurt. OW. Pretty sure it's caused by the drug, but right now, dealing with it."
