I've added a muscle relaxant to my meds to help deal with the intense spasms that I am currently suffering so I am managing a little better but it now means I take around 140 pain killers per week �� at the moment my kidneys etc seems to be unaffected but you have to wonder how long that will be the case. I hope you have found some relief from your pain. Chronic pain is something I would not wish on my worst enemy ��
