Hey everyone, I have a question I hope I can get answered. About 2 months ago, a friend pointed out that I had a fairly large vein on my right temple and I went home to take a look. Sure enough, there it was. I've been monitoring it closely and have been talking to a couple people about it. They feel it's normal but I'm a bit concerned. In normal conditions (i.e not too hot) the vein is barely visable but when it gets hot or if i run or something along those lines, it potrudes and pulsates. Today I was driving in a hot car and the vein became visible again. I stopped near a well shaded, cool area expecting it to receed. Instead, it proceeded to stay there and pulsate for nearly an hour even though the rest of my body felt comfortable and rested. I was wondering what might cause this. Is it stress, diet, what? Part of me wants to say it's normal due to the heat, but I've never seen it before so I'm a bit worried. Thanks all.
