I haven't been on the bike since last week. I have a pinched nerve in my upper back. I fell asleep watching TV last Friday night with my neck in an awkward position. The last few days have not been fun. I've since learned that pinched nerves are painful and lead to numbness. In my case the numbess runs down my right arm and into my thumb. The pain has since subsided a little, but the numbness is still there. Until it comes back, I'll be laying low -- and driving.
