I've had a tingling burning pain in my left arm around my elbow and down my forearm for the past 3 months and it just hasn't gone away. It often feels like an the sensation of an injury -like the skin has been scraped off and the muscle has been cut and is trying to heal- but I've had no injury there. Just wondered whether anyone else has anything similar and might know what it is? Is it inflammation in the muscle? It's often worse when I'm tired and I get muscle weakness at the same time.
