I have been experiencing chronicc knee pain for more than 20 years. I have had three surgeries on my right knee arthroscopicy. elmslie trillat, & lateral release) and one on my left (lateral release). My pain really has not been diagnosed. I have seen many orthopedicc specialist and a rhometolgist. Xrays, MRIs, & theblood workk for the R factor have all been negative. We are now going to do an EMG to check on the nerves in my knees. Does anyone how any ideas that we can explore.
