Hello, Im 16 and for the past month, my heart beat has been visible in my throat and the sides of my neck. The strength of the beat usually varies but is random. It all started after I started going to the gym a month ago and is worst days after working out. Occasionally like today my throat has been feeling a bit weird like its blocked or swallowed or something. Few days ago I overworked myself in the gym as I was nauseous and felt a vomiting feeling in my throat. The problem of the heart beat in the throat went away last week for about 5 days last week before starting up again 2 days ago. Along with this I just noticed my chest and stomach faintly moving in the pace of my heartbeat just today and this is why im concerned as i had never notcied that before so I assume it has spead. Anyone know whats up Im extremely concerned my heart may fail on me or something haha
