Firstly I'd say don't train hitting things without support or mits. Not until you've condtioned your wrists more and learnt the correct striking methods.
As for healing as Wu Ming she is good with all that stuff but I would say rest it up for a week or so not doing anything much. Massage and lightly rotate 2-3 times a day for bout 5 mins.
Gradualy increase the exercise in week 2, squeeze a tennis balls for a few mins 2-3 times a day or someone has suggested before use putty...
Be aware of the pain and cater to it. Try not to get frustrated and force things to move quickly...
Focus your mind to repairing things internally and visualise it happening quickly.
I'm sure a few herbs and suppliments will help but I don't know names sorry again ask wu ming

but i'm sure she'll post anyway
I'd say wrist your look at bout 3 weeks as a minimum but still take it easy on it.
Read books while you rest and expand your minds knowledge on your art... watch videos... meditate
