I have been riding about 35mi with my club every Sat plus shorter weekday rides and although I had a pro bike fit I had to do a little tweaking. I had sore elbows and I fixed that by nudging the seat forward and working on engagingmy core and keeping relaxed elbows and shoulders. Everything has been great the last few rides.

Then yesterday I had constant numbness in my hands that I've never had before. I had to keep shaking them out to have feeling. Once I got home my hands felt so weak I was having trouble washing dishes.

What is going on?
