i am a 44 yr old female with high cholesterol in the upper 200's, i am 5'5" and weight 200lbs. i was diagnosed with having 60% carotied artery blockage.... i had a lexi scan done with negative results. i have had a lung scan done with & without dye with negative results, an upper GI with negative results. my question is this: each time i walk a distance or do something physical i get a burning sensation in the base of my neck where one would put a trach tube, this burning will continue up both left/right sides of my neck and then proceede to the middle of my chest, if i take the time out to rest it will go away if do not it get worse and worse until i can't stand it. i have had numerous tests done with no results my old primary doctor insisted this was an anxiety attack but this never happens with stress only physical activity and it is now even starting to happen during sexual intercourse. does anyone know what could be happening to me? i feel like giving up and letting nature take its course.... could this be because of the heart trying to pump the blood through my carotid arteries and when it meets the resistance (clogged area) it is back flowing causing this pain?
