yoga and pain

I went to yoga class this morning at 24Hr. Yes, I still have membership. I only pay $49 per year, so I'm keeping it. It's such an amazing deal. When I was doing one of the poses my old running injury flared up. I couldn't do the adductor leg raises in the air while standing without feeling a bit of sharp pain. Uh oh! It's definitely a sign that I need to start doing my physical therapy exercises again. I was in PT for 5 months originally after my Chicago marathon training. I definitely don't want to do that again:(. I pulled my groin muscle about 2 years ago. I signed up for the San Jose Rock n Roll Half, so I better be able to run it.
