I've been doing somethig different with my left hand, trying to keep a stretch, and I've noticed a strange feeling above my elbow. It's not quite painful but it feels like a strange pull. It feels like my vein is being pulled... I see the vein and I don't see it on my right arm... There is an indentation where the vein is. Since I noticed that, I realized that the pull sensation is always there. For the last week or two, I've been always feeling like the blood doesn't get to my left hand, and my hand has been falling asleep all the time. Is this something I should be concerned about... ? Don't really feel like going to the doctor to check it out... but maybe I should. My step father mentioned something about blood pressure when I showed it to him, but he likes to scare me.. ?
