My husband had a hard blow to his shin/calf area by a line drive baseball, during baseball hitting practice earlier today. He proceeded to play 11 holes of golf a few hours later, where he could hardly bare any weight on his leg and he could not continue his round. There is a huge large swollen area, but no visible bruise in the area where the baseball hit him. The swollen area is hot to the touch, and the surrounding area is cold, even a half hour after icing it. He is concerned that it may be broken/fractured. It is a holiday weekend. What should I do?
