Been having a visible neck vein,on my right side,when i touch it i feel heart beats,it is not painful but it makes me feel really uneasy and lowers my self esteem..can anything be done to make it not visible?

You could be seeing pulsation in your artery rather than the vein because the arteries are easier to feel than veins. It is possible that what your are seeing are veins. In either case, it may be be completely benign, but this this decision can only be made by a physician, especially one who knows you. Least esteem is the least important reason to get this evaluated. Visible neck veins are normal.

Yes. Find out cause. And correct that.
