Hi There, I Was Playing Indoor Football 4 Months Ago

Hi there, I was playing indoor football 4 months ago and I kicked a ball very hard and felt a pain in my right leg, to be precise where the belly meets your leg. It was very hard to move my leg, I started putting some cream to ease the pain ( deep heat) and after 4 months I started to work out and do some sprints. I can only feel tiny pain but I feel my leg is okay now and im ready to play again. what advice can you give me .. Thanks
