Can anyone Please tell me why There would be "Pulsating" veins or arteries in the left side of neck? I asked before but this is getting worrisome, my heart monitor so far is not showing anything I was told, but I can actually see it thumping or pulsating! I actually took a video of it today. Im hoping its just spasms or something but i have no idea what to think, ive only talked to cardiologist nurse over phone since all this. im going to try sending video to dr. tomorrow, i need answers its been almost 2 weeks of symptoms
