I decided not to race tonight. I called the physio who seems to think it's my back. I guess the sciatic nerve might have been crushed. It's strange that it also affect my wrist, arm, and leg ... but I know it's all linked.
I am seeing the physio tomorrow ... I hope all is ok .. because I am in good form and I really want to get out on the bike again soon.
I will keep the thread updated.

Cheers
