Hi all - I usually hang out on the Multiple Sclerosis forum here, but Jo55 gave me a link over here to check out something going on with my left arm.

I have been having trouble for a few months now. This seems to have started in my biceps and is now all down my arm and some of my fingers are joining the party. The main issue is that if I use the arm too much, the bicep starts to spasm and tighten (this is painful and annoying) then intense tingling and numbness spreads down my arm. In the beginning, I don't remember it traveling down the arm, but seemed to be more just the bicep.

I had nerve conduction studies done and it shows slowing in the median nerve. My PCP is calling this carpal tunnel. However, the more I look at carpal tunnel, the more it doesn't seem to fit. I don't have problems more at night nor do I wake up because of this. Also, I don't have pain in my wrist / fingers.

I looked into TOS after Jo55 posted on my other thread on the MS forum and it seems to be more of a fit to my symptoms. Also, I should state that I am a small framed woman with large breasts and that seems to be a risk factor for this.

All of the above was really just background. My actual question is regarding something bizarre that I have been experiencing. I notice that if I turn my head to the left (my left arm is the affected arm) and and lean back to stretch, I can feel this pulling from my shoulder (from a particular spot on the inside of my shoulder) down to the crook of my elbow. I don't experience this on the right at all. Does this sound like something any of you experience that is related to TOS?
