Hello, I have been having burning pains in my stomach, feels like the lining of my stomach, it can burn for a few seconds or a minute and then it goes away but will keep coming and going, I have been having hot sweats and cold chills, as well as Dhiarrea (mostly liquid) I have had this before but I can go a year or more without this pain and then out of the blue it just starts up. I also when sitting on the toilet will have a horrible anal cramp? I start to get nauseous, dizzy, light headed, and of course my anus hurts bad like its contracting, I feel like I'm going to pass out and die. It is awful pain.
