Pulled adductor muscle in leg.

I am not sure wether or not this is the place to be asking but, I have been in the Martial Arts for about half a year now and several months ago while I was on the splits strech machine, I felt a pop or something like a tear on the inside of my leg on what I am pretty sure is the adductor muscle. This happened last november and every time I try to do my kicks or the splits, I feel that pain in that area on my leg. Can anyone please tell me what I should do?
