See doctor: Have it evaluated right away, assuming no trauma, he is either suffering from a clot to the leg or an infection called cellulitis. Either way he needs prompt attention.

Might be blood clot: Uneven (l-to-r) swelling of an extremity with warmth & tenderness is very suspicious for a dvt. Should see your primary dr or go to er for evaluation so can begin treatment.

Swollen leg: The most likely diagnosis of cellulitis, and should be rapidly evaluated either at an urgent care Center, or emergency room. Often fungus from the toes can stimulate the cellulitis.
