Well, NGL, this sucks. MRI to confirm tomorrow, but the doc's pretty sure I have a complete separation of the tendon connecting my biceps on my right arm to the elbow

. Apparently, this is an issue that can manifest in active adults in their 40s and 50s. So, uh, be aware of it. For me, I was working on my garage lifting a sheet of fire-rated sheathing, and felt multiple pops in my arm.
Assuming surgery, so looks like I'm off the water for this fall most likely
on the OTHER elbow, I got tendonitis of the bicep tendon too. I swear, I'm falling to pieces!
