Thanks again for the response, I will keep doing the icing and the stretch exercise you suggested.
I should stress that I never even try typing etc, because it really is so sensitive that the pain quicky reoccurs. I have no neck pain, the pain only flows down from the sore spot into my fingers when it's really bad so I havn't triggered it to this point in a while. As far as I remember I could feel a slight burning in the back of all of them. Sometimes I get a strange sensation where my two rightest fingers feel as if they want to stretch out away from the rest of my hand. The sore spot is clearly the cause of all of it though as far as I'm aware of.
