Brief update to my post above. I'm now 4.5 months out from the initial injury. Pain has been completely gone for ~2 months now, excepting a rare soreness in my L forearm... though I question if I'm imagining it.
All tingling/numbness is gone.
The most important part: L triceps strength. I think for most of us that's the scariest aspect, the possibility that we may have permanent weakness. The good news is that this strength has returned significantly. I've been following with push-ups. For the first 1-2 months, I couldn't even do one push-up. Very defeating. Now, 4.5 months out, I can get up to 10 push-ups, albeit having to favor my other arm. Prior to the injury, I'd generally do 20 push-ups in a row. Not sure I'll get back to that, but am hopeful I'll continue to improve. Now that life is pretty much back to normal, I'm more patient with my progress. Studies have shown that most people are back to normal at 2 years. I'm willing to give it that long barring a repeat insult. That said, if it occurs again to the same extent, I'll probably opt to go straight to surgery.
