Tingling of left arm from deltoid down to finger tips
by C.S
Started: July 16th July 23: Went to ER. Took CT scan of head and drew blood for blood count. Both results came back normal. July 26: Saw neurologist for consultation and examination in his office. July 28: Neurologist recommended MRI of head and neck. Both results came back normal. August 2: Saw neurologist in his office for nerve testing. Both result of EMG(elctromyography) and nerve conduction studies came back normal. Tingling started from the deltoid area down to the finger tips which lasted a several seconds(approximately 20 seconds) without pain or numbness. As soon as tingling started, I raised my arm up, and the tingling is gone in about 4 seconds. What is causing this tingling? Hello CS, Obviously without a good clinical examination, it's impossible to be certain. Even then it's difficult to say with 100% certainty. The fact that raising your arm relieves the tingling is a strong pointer: "Shoulder abduction relief sign". Raising your arm takes the tension off the nerve root / brachial plexus, relieving the irritation. A classic sign. However you make no mention of neck pain, or whether movements of the neck increase / relieve the tingling. Also: which fingers, that gives some very definite clues as to where we should be looking. Try a brachial tension test. Stretch your right arm out to the right, palm forwards, and then extend the wrist. Remember the tension in the forearm. Repeat with the naughty arm. Is it any different? Repeat, tilting the head and neck to the opposite side. Turn your head and neck to the left, and then look up. Anything in the neck or arm? Try doing some pressups. Does the triceps on the left tire much faster? Let me know and we can take this further. Meantime, avoid carrying anything heavy in the left arm. Try not to sneeze. Dr B |
