Hernia or Pulled Muscle?

 Thur. while at a kickboxing class I got a terrible burning pain just below my belly button.  It lasted about a minute.  When I would move certain ways it would hurt but was able to finish the class.  Well since then Im still having this burning pain in the same place when I move certain ways.  Do you think I just pulled a muscle or did I tear something????  If it is just a pulled muscle, what should I do to speed the recovery?  I will call my surgeon Mon. & make an appt. but was just curious what you guys thought.  Thanks for any input!  

 I'm going with pulled muscle.  I would try ice but if heat feels better-go with it.
