My Hubby (45) hurt his right leg (thigh) after a rather rough tackle in 5-a-side football. After about a week some large bruises appeared and he was still limping. A few days later his thigh has swollen up a little. Probably water retention. I know you're going to say "go to the Doctors" but would prefer to treat it at home. Does he need to sit with his foot raised on a chair? What else can he do to help it?
