Medical Update 9/16/22:
Turns out I'm not going to need an MRI on my neck. Saw my spine surgeon yesterday about my left hand pain and numbness. He did some tests and - I swear I don't know how I missed this - he figured out that the muscles in my hand are wasting away! He diagnosed me with Left Hand Wasting, Cubital Tunnel Syndrome on the left, and Bilateral Carpal Tunnel Syndrome. I've been referred to an arm & hand surgeon.
