and 40mgx1 oxycontin until i notice if lyrica works). I told him that the oxy contin was only lasting 6hrs not the 12hrs that it is required to last. He said i've become tolerant of the oxycontin and its not working for me anymore & there was no use increasing it as it was already a high dose per day. When i looked up lyrica it said it was to treat neuropathic pain which is caused by nerve damage. I wouldn't have thought bone on bone severe osteoarthritis in both knees would require medication thats for nerve pain problems. Any help would be great thanks. Also i would have asked him at consultation but he said he was just changing meds from the oxy that wasn't lasting more than 6hrs to one that would last much longer.
