I had rhabdomyolysis in high school after an intense afternoon of running around in the cold. Let me describe the pain:

* everytime I breathe in or down I felt like screaming

* moving almost any part of my body even an inch made me scream

* my urine was dark red

All my life I've had above normal pain tolerance from another chronic illness but it took rhabdomyolysis to really break me--quite literally. Ultimately it resulted in being put in a stretcher as I screamed my ass off.

It took a lot of morphine to find any relief and dialysis to fully recover.
