I am having a very strange reaction when I swallow food and also some drinks . I will have a severe nausea feeling ( similar to the feeling of just before you vomit ) I feel as if I am about to pass out at times from the dizzy effect . It comes on a few seconds after I swallow food and will last for between 5 - 20 seconds and then slowly easy off . It came on very quickly as I had not had this before and have now had it for a week . Every time I eat something it happens . I have read a bit on Google about a thing called " swallowing syncope " but hope that I dont have that as its quite serious from the looks of things . I have yet to black out , but at times I feel like I am very close to it . Any ideas ?
