Ive been getting complete numbness in my left hand solely in my pinky and ring finger (medical terms), on rides after about 30 miles. It lasts for a day or so. It doesnt hurt, and wouldnt really bother me if I wasnt a working guitarist. What is usually the cause of finger numbness? Could it just be a pinched nerve im aggrivating? Any doctor/cyclists out there? Did I spell aggrivating right? Im asking here because, well, I like you guys the best.
