It appears that the handstand workshop had a bit more of an impact on my wrist than I thought.
Left wrist, tendons on the thumb and index finger hurt considerably when flexed back.
I'm thinking this is lack of flexibility antagonised by considerable hardening up in the grippy direction from a number of years climbing.
They probably need to be stretched progressivly rather than be subjected to 2hours of abuse immediatly.
I've already booked myself into the tumbing course on tuesday, but think I may need the week off to ice it and rest.
If I can cancel I will, but we'll see.
Have been direct icing it, so theoretically, that plus rest should sort me quite soon.
