P.S You may have Carpel Tunnel Syndrom. This is caused from the medial nerve that runs all the way down your arm and into your wrist. For example when the nerve is piched at your wrist it causes the burning. It shoots up and down your arm. It sounds like an onset, if the doctor cant find anything. My mother had the problem and she had surgery on shoulder. Sinse I sent you the info above, If choose to see a massage therpist, tell him/her to take it easy you probably have a knot above scapula.
Your check-up was fine, still you have that burning feeling. they say that aneurysms usually occure in aabdominal and thoracic area, occasionally cranial. I am no doctor but I am a Massaage Therapist, and since the problem has started up agin the burning down your arm, I would again get 2nd oppoion. And if thumbs are up, you get the green light, this is what you do... see a massage therpist, you may just have some nerves that are cought in muscle and irrated, first check around so you just dont get any old therapist get a recommendation from a frind, chiropractic, ect.Honestly the burning usually is coused from tendonitis.
