I feel you, man. About 5 months ago, I decided to fight through the pain of a strong body triangle. My opponent had my back and was trying to finish with a RNC. His choke wasn't secured so, I was trying to turn my body to face him, and I felt this abdominal pain that felt very much like a break. I've broken a rib before, so I know how it feels.
Went to the hospital, and got x rays to find out that it wasn't broken....just SUPER bruised, but that was cool because it meant just a few weeks down instead of a few months. During the time between the pain and the x ray, I was freaking out that I would be one the shelf for a while with Jiujitsu.
It ultimately taught me to respect body triangles as much as I do a choke.
