My husband is a gas meter reader. He has been walking in the snow past his knees. He now has pain on the left side of his groin. In the past week he had to squat to pea because if felt better than standing. He said it was the force pushing when he peas that was uncomfortable. He walks through the snow 5 to 6 hours a day. Is this just a pulled muscle in his groin or something else to be checked out. Now going on 3 weeks of discomfort.
