the left hand and arm numbness and tingling sensation started just a week ago. It is accompanied by muscle weakness in the left arm and popping from the shoulder joint. It is constant in nature. It happens while working or more severe at rest. There is no accompanying pain.
I know this is of little help but I too have identical symptoms to yourself. My doctor is sending me to have a test for carpal tunnel but I am doubtful of this as the symptoms for that is pain and burning in the hand and fingers. Perhaps you too could go to your doctors and they may be of more help to you then mine was. I'll keep you posted if I find out more.
