[|Human|] I have burning in both legs seeming to originate at inside of my knees. I fell in September and injured my left knee no apparent tears. Xrays show arthritis in left knee. I also have the beginning of a bulging vein in my left thigh that is tender to touch. I can only sleep flat on my back. Have pain when legs rest on top of each other when trying to sleep on either side.
[|AI|]  Hi, Burning sensation in the legs and knees could be due to neural compression of nerves at the spine. You need a thorough examination, and investigations like MRI of the LS spine and thoracic spine, to see if the nerve roots are at fault. The treatment of this condition could be both surgical and non-surgical depending on the findings seen on investigations and examination. I advise for you is to see an expert spine surgeon first, and if he rules out, then a peripheral nerve surgeon.
