Tramadol has been the 'wonder drug' for me with cronic pain relief in my arthritic knee without the typic narcotic side effects... I know this drug is relatively new - 1995 I believe, but have there been any recent studies on the drug if taken long term... Or for that matter any studies at all that have been made public.. Especially what it may be doing to our organs... It's a unique pain med that's prescribed often for pain and I am very curious.. Thanks and comments welcome..
