I was suddenly choking. I choked and couldn't even keep water down for a few hours. Suddenly I barfed out some Peanut M&Ms I had eaten about 7 hours earlier and now I feel fine. Why does stuff like this happen to me?!
A food allergy also sometimes can make your hands, feet, face, ect swell and red bumps may form. I've had it happen to me when wearing latex or eating pistachios.
My step-dad had a blockage in his esophagus that turned out to be cancer. He passed away about 11 years ago. So you should get it checked to make sure it isn't something serious.
