Still Out Of Action - OTTB

My hamstring muscle is still not healed. I have had ultra sound treatments and hippotherapy, both of which made it feel better, but as soon as I try to go on with my previous activities (walking the dog, swimming pool maintenance, etc.,) the muscle seizes up  again. I was suppose to have a lesson with Eileen this morning, but it was canceled because of my leg. Right now I am having trouble walking, so I didn't go to the farm at all.
