question: I have these episodes that begin when i feel i need to have a bowel movement. I get severe stomach cramps and find it hard to go. At the same time I start experiencing my heart rate elevate as well as my blood pressure to the point I feel as if someone has tied a rope around my neck. My eyes feel as if they are bulging and my ears feel like they are about to explode. I turn bright red from the neck up and the inside (roof) of my mouth becomes numb. This lasts only for a few minutes, some times longer depending on the severity of my cramps. After wards I experience extreme headaches, tiredness and pain.
