Hi,I m male, 43, 178cm, 82kgs, I ve had in the past very bad lower disc trouble but with the proper treatment and continued exercise it s in pretty good shape now. At the time I was prescribed OxyContin 10mgs which after 4 years was at 100mgs but this was 3 years ago. At the time I also had numbness is 4th and 5th fingers on both hands which I put down to the potency of morphine. However after stopping all painkillers I still have the numbness even now. It didn t worry me too much but 2 months I also started to feel weakness in my right arm up to the shoulder. When working over head I can t keep my arm up very long with out complete drop from weakness. Now the severity of it ranges from not being able to lift a full kettle of water, to my hand dropping a towel on some days. When I try to force my arm to lift something, my forearm and bicep muscles feel pressure and my hand just hangs from the wrist. I take Lyrica 100mgs up to 4 x daily on days when my back feels overworked or to relieve the numbness of fingers. I don t really have other symptoms except maybe feeling tired a lot of the time. I work construction so as you can imagine my arm is really causing a problem for me. Thank you in advance, Ger.
