It is either the overload of Mcdonald's or the overeating, or the lack of exercise that is causing it, but I felt a contraction in my chest today. It wasn't a drawn out contraction, just felt like a lump of food was stuck in my lungs for a couple of minutes, very much like how the oesophagus feels when you swallow a large chunk peanut buttered bread too quickly without sufficient chewing.

I hope it is nothing serious.
