yesterday, my stomache was not feeling very well. I went to the bathroom feeling like I may have some diarrhea. While I was trying to go, I was hit with this incredible abdominal pain. It felt like a contraction during pregnancy. they were a 10 out of 10 on the pain scale. I started to feel very faint. My vision started to turn white. My arms felt like they weighed a ton. My ears didn't ring but instead had a scratching sound like when a record is done playing. I had to lay on the floor of my bathroom for quite a while until I felt better. I have had this happen before but not very often, like once or twice a year. I have no idea what it is. I am healthy, not on any medication, and not pregnant . Any ideas?
