I have tightness around my collar bone. A sort of weight around my neck and I have always had tendency to choke but not always. However, although there is no pain of any type, I feel constricted as though someone was trying to choke me or had a tight necklace around the neck. I have been taking vitamins. Although not insured now as unemployed I did get complete blood word recently. The only negative results were my cholesterol level 290 and the Bun/Creatin ratio levels were at 30.4 (H) and I was simply told to go to urologist. I have not gone but cannot see how this would be related to any of that. My diet is not the best and I am overweight which I am trying to control by walks as I hardly exercise. - I am a bit concerned about the throat issue and would like to know if thyroid is a possibility besides the allergic reaction possibility. However, either way I have had no history of allergies except to dust or pollen when excessive. I may developed one nonetheless to something to which I am totally unaware.
