Sounds like you have carpo tunnel or however you spell it. I have it too. Sounds exactly the same... Can really do much for it without surgery but tht usually doesn't work either. Use ibuprofen. Or aleve.

I also have an issue with the inside of my elbow it's kind of like the inside of my elbow not the joint but when I flex my forearm it hurts... Kind of like a tendon. It's been hurting for months. Ever since I threw up 365 2 times haha
