Hi8 months back steel pipe hit my left elbow after that I didn't feel any pain. Slowly now pain is there in elbow and left arm till palm and finger and also left shoulder n upper left back. Crawling feeling sometimes on left upper back near neck region. Burning feel on elbow area and also arm. If I do any heavy work it started getting pain on left hand and shoulder and back. Meanwhile if climate is cool my left hand s burning and if I tie with blanket it was ok. Suggest somethiNg for this.
