Am now six weeks post op and have lots of pain in knee just like a bunch of stinging nettles with sharp shooting pain going through, the same day and night nothing helps, ice packs, heat pads, painkillers,I have just tried acupuncture first go, as it appears my prothesis is working ok apart from "clonking" as I walk, the orthopods dont want to know, anyone any ideas? It is as if my nerve endings are just under the skin and very sensitive
