K.B.
The worst pain of my life.
Very intense, centered in the middle of my upper abdomen but radiating around to my back. Often triggered by eating fatty or greasy foods, kicking the gall bladder into high-gear, and moving any gall stones that happened to be present through the bile duct, which is what causes all the pain.
Typically would last around 10 minutes, then would stop on it's own, sometimes after vomiting a few times. Made me feel like I wanted to die. Not fun at all.
Got diagnosed on ultrasound, then bye-bye gall bladder. No problems ever since.
