Ouch.
I can relate.
Interesting side discussion.
When I am riding my mountain bike, from time to time I will experience mild numbness in the fingers of my left hand, usually the pinky. But like RUinPinehurst, I am not into procedures either, or meds for that matter. It goes to my Polish roots I guess. But when the numbness crops up while riding, I can make it go away (or subside quite a bit), by sitting upright and arching my back. I have made it a priority to work out my core and back muscles (hollows, dragonflys, weighted crunch, deadlifts, bent over rows, pullups, pulldowns, etc.) and it makes a bit of a difference. Also spend a lot more time stretching my tight hamstrings and on ankle dorsiflexion stretches.
