Rest. Maybe some IBprofein. That is a painful injury. I pulled my groin a few times in my life and it can be very uncomfortable. I would assume that a tear would be worse. I had thumping in the muscle all night long when it was pulled. One tip if you use Biofreeze or Icey hot on the injured area be very careful or you may wake up in the middle of the night with another type of pain. LOL Get some rest.
