Went out yesterday for a 12 mile ride. I have Reynaud's condition which makes my hands very painful in the very cold weather, and wear lobster claw gloves, which normally help.
They were little help and, by the time I got home I could hardly shift the gears or pull the brakes I was in so much pain. It didn't help that I wasn't wearing my heaviest jacket.
I went from the freezing cold into a very hot kitchen and had to go for a lie down on the sofa because of the dizziness that hit me.
It's happened just once before and I really should learn from my mistakes.
