I am a 58 year old, lifetime athletic male of appropriate weight. Over the last 2 years, red and brown spots and areas have begun forming on both legs, but primarily the left leg, with swelling in the calf and ankle on the left primarily. I have also noticed frequent cramping of the calf muscle. Close inspection reveals some surface level veins, possibly vericose. Is this of great concern, or a natural process of aging and being on my feet a lot (I am a trial attorney). They do not hurt when I run or exercise.
