Suggest Treatment For Bruises On The Calf

For about a week I have had a 3 hot spot on the outside of my left calf. There is some pain when touched, but not much more than if it was slightly bruised where the top of my socks end. There is no swelling or discoloration. I am 65, 6 foot, 205 pounds and use an elliptical training machine 45 minutes, 5 days a week, during which time I try to keep my heart rate below 140. My PB is read twice a week and hovers about 135/65. I see my doctor every year and he says that I am in good health. I do not drink any alcohol, and I have never smoked. I am curious about the heat in my leg.
