My kindney is shutting down

GRRRR…. PAIN!
I’m sitting here is pain, pain like I haven’t felt in a long time. I think i pulled a muscle on the right side of my back. It hurts deep inside, like I broke a rib…. But I haven’t gotten hit in the ribs in a long time. Im thinking that I pulled a muscle moshing on Saturday night for plague: The red letters at Koos, or my right kidney is shutting down. Either way it sucks. The show on Saturday was fun though. I like the new Koos.
