My Husband Pulled A Muscle In His Leg, Possibly Groin,

My husband pulled a muscle in his leg, possibly groin, while refereeing a football game over a month ago. We have done ice, wraps, Tylenol and resting. He feels really good at times and thinks he's on the mend! Then it starts all over again. It's starting to effect his gait and now he has pain in his shin. He is reluctant to go to Dr.
