Pain in hand and knee

Hi,

I have two similar questions.

1: When I'm playing a forehand counter-hit or a forehand topspin, actually just any forehand, for quite a long time. I get pain in my hand. It's in the middle of my hand just between two bones. But the strange thing is that I only get this pain when I play forehand for quite some time. 
I have had a fracture twice, both my right forearm and the second time almost went wrong. I broke both the bones in my forearm and my arm was 'out of shape'. I still can't move my wrist like the way it should, I can't turn in fully to the left and right and I can't make a 90 degree angle with my wrist up. Maybe this is why I feel this pain, but maybe I'm just using the wrong technique. 

2: Well I'm right handed and when I play I sometimes get pain in my left knee. But I never asked my trainer about that and I never got told that my footwork isn't the way it's supposed to be. But I guess I'm not the only table tennis player with pain in his/her knees, do you have any tips?

Sorry for the long question.

Hi Izzy,

It is probably good if you go and see a doctor about this.  What you could try first though is to try holding the bat a lot looser.  You can have the bat so you are just hanging on to it enough to keep it in your hand.

Again with your knee go and see a doctor.  There may be some simple things that you can do. It is always best to get them checked first though.
