I agree that it feels like it needs blood in it, but think about it - if your limb was really lacking in blood, I think it would look and react a little different than it does. you can still move it, it just feels weird. it feels weird b/c of the nerve crimping

"That which does not kill me, will make me stronger"

Carpal Tunnel Syndrome, or any other inpingement of the median nerve,
can be distinguished by weakness, tingling or numbness it the area of the
thumb and index finger. If the pain etc. extends beyond the middle finger
into the ring and little fingers, chances are it isn't CTS. The symptoms
you describe indicate nerve involvement. Thoracic outlet (TOS) isn't recognized
by some medical professionals, but have them check you out for it. The noninvasive
tests for TOS involve monitoring the radial pulse in serveral different
positions. Request Allen's, Adson's, hyperextension and hyperabduction tests.
If any of these positions cause a reduction in the radial pulse, it is a
positive sign for TOS. The definitive test is an MRI. The only treatments
I can recommend is to stretch your pec minor and scalene muscles. The medics
may order a nerve conduction velocity test. If they do, I myself would be
tempted to decline it and go straight for the MRI. NCV tests hurt like hell
and aren't really diagnostic in cases like these. I think TOS may be aggravated
by cycles, or by water retention, an it is aggravated by the forward-head/rounded
shoulders many bros develop from overworking chest muscles so that they
are imbalanced to their back muscles. Good shoulders back, head directly
over shoulders posture helps. If the neurosurgeon can't offer a clear diagnosis,
request physical therapy preferably from a PT with an orthopedic specialty.
