Why do the veins in my hand bulge easily and frequently? 19 yr old male, 130 lbs, 6'3", diagnosed with generalized anxiety last year. My left hand veins bulge more easily than the right and it's usually the one running down the middle. I just started noticing this this week. I also noticed one on my palm between the wrist and thumb today after a brisk 7 minute walk. A mild tightness accompanies it but the discomfort is very minor. Haven't exercised much since the chest pains and such from my anxiety for the past year. It's frequent, but not constant. Only drink water and have been eating healthier since experiencing generalized anxiety and occasional panic attacks. I also noticed two purple veins in the back of my throat, but I've been told that's normal.

I heard somewhere if you put pressure on the fingers it helps determine if there's an embolism or something. I tried it and the color returned instantly, but I question that.

Thanks for your time.
