When I am speaking normally, it will come out. Only my left, not my right. I am 16, female, slim, and healthy. I have a somewhat bad posture with my shoulders and back area. Every once in a while, I get irregular heartbeats for 2 seconds. Do they affect how my neck vein shows? Is there any surgery I can get to hide my neck vein? I am very insecure about it. Please please reply as soon as possible, thank you.
