Weakness vs "feeling of weakness"

[ptich]

My left arm does not have objective weakness, but I am getting some neuro "feelings" of weakness that hard to describe, especially when I position my arm in a certain way. The "feelings" seems to be mostly related to the Ulnar nerve, as they usually come from the elbow down.

Also I noticed couple of times my thumb, and index finger, were jerking at the ferquency of the heartbeat, and it was accompanied by the "shooting" feelings just down of the elbow.

I was wondering if this is how weakness gradually comes to an arm.

I had mild carpal tunnel and ulnar nerve entrapment, low and behold from constantly holding my head up with my elbow down and my head resting on my wrist!! If you get numb and tingling hands especially at night or burning pain that radiates down your forearm to your finger tips, then you more than likely have an entrapment....
