I'm a personal trainer and i'm telling you there are ways to work around almost any injury and I'm glad you have, your PT was an absolute joke and it annoys me how easy it is to get certified these days there where some complete morons on my course and everyone of them made it through as you...
Happened to me for a good few weeks like someone had given me a major charlie horse, its just your muscle not being used to having the oil and chemicals in there on other boards i've heard it referred to as virgin muscle syndrome your good to go
