I have a vein running up my neck to my chin. it is blue but not real bright. it is visible though. it is slightly right to the middle of my neck. im 43 had an echo, blood work, and ekg recently for pvcs. should i be concerned? is it normal to see?

It is not feasible to provide a meaningful opinion without additional history, and physical examination, however, from what you described, it is not a cause for concern. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
