Tonight, I was able to strum along to REM's "What's the Frequency, Kenneth?" and "Find the River", back to back.
It wasn't easy, nor completely painless, but I did it, which is an achievement.
The finger is gnarly with rivulets of scar tissue on the pad, and where there's scar tissue, there's very little feeling. Immediately outside the scars it hurts. A lot.
It's getting better, and being able to play La Pistola, even if only for a bit, brings me happiness. Hopefully within a few months I'll either have healed enough or otherwise gotten used to the nerve damage sensation enough to play back to my old level.
