Ever since I was a little kid (Im 32 now), Ive had a bright green vein running up my right arm all the way up across my chest above & in to my right breast. I have green veins that are visible all over my arms and on my face (not as prominent there) & little bluish veins on my neck & and arms. Doctors have seen them & never said anything. The one on my right arm & chest/breast are so bright that when I wore tank tops people would think I drew on myself with a green marker. My O2 is always good although I havent had it checked in a couple years. My blood pressure is usually around 120/62 the highest its ever been is 180/75 cause I was in excruciating pain from a torn tendon in my back. I smoke about 1/2 pack of cigarettes a day. I dont drink alot or do any drugs. Im overweight but not unhealthy. My cholesterol is good & Ive had EKGs and my heart is good. I do have alot of stress right now & panic attacks that cause hyperventilation. And really bad muscle spasms in my neck and traps & pectorial muscles. Anyway, sorry for the rambling post. Just wanting to know if anyone has this too & what it is.
