Yeah I figure stretching can't hurt, only help!
When this all first started, I thought it was just a headache problem because I was having balance issues along with it. I did not make the connection of it possibly being a muscle out of whack.
Hmm...that is a good idea too, to try to learn the other style of knitting. That might help if I am using my other hand more (I am right handed).
I need to get a tennis ball!
