Basically 3 weeks ago i contracted something called gastritis. This can be caused by a number of reasons, bacterial infection, prolonged constipation...yyadaa yadaa yadaa. So basically what happens is that the walls of the stomach/intestine become inflamed and thus when food or such passes through them, it hurts. goddamit it hurts right now. shit.
Anyway. This is what gastritis looks like in your tummy
