Hi, I am new to mountain biking. I've only ridden about 5 or 6 times maybe about 20 miles. Some of the terrain has been pretty rough, the longest trail was good and clear. The first time I didn't use gloves and got a major blister on my hand which is better now. The thing bothering me now is some major thumb pain. It doesn't seem to be the the joint connected to my hand but the joint in the thumb. It almost feels jammed. When I stretch my arms it tingles. I did have surgey on my hand like five years ago for breaking the bone connected to my ring finger which is loaded with tiny screws. I rembember having some thumb pain after my second surgery when they did a bone graft on my wrist. I'm not sure if that is related or if this a common ailment among new bikers so I thought I'd ask here if anyone else experienced this problem.
