Thanks for input. No diabetes, etc for me. I suppose excessive cycling is relative to the person. I have ridden an estimated 150,000 miles over the last 35 yrs, most of it ridden very hard. It's going to be hard to reverse most of the damage.
Neurologist is on the horizon - just been putting it off. Family doc diagnosed many yrs ago - no doubt she is correct. I've read that relief is often difficult to obtain. Many meds are ineffective with unpleasant side effects, which is the kind of input I've been looking for. I use Look pedal system. Do not like SPD.
