I made an appointment with a doctor to get checked out. After some testing, he determined that I would need carpal tunnel release surgery to hopefully restore my hand. Yes, carpal tunnel surgery is very common. My main point in writing this to point out to other drummers to get these hand pains checked out if they persist. It is possible to damage the nerve beyond full repair.
Obviously, this is nowhere near as bad as my hand surgery from last year. Read about that here. I will post a few more updates as things progress. Also, new content will resume as healing permits. As for now, healing begins!
