I am a 65-year-old man in good physical condition, with low cholestorol, blood pressure, and pulse (under 55 BPM). However, I have an egg-shaped lump on my left leg, just below the knee. I also have bruising on my left ankle. Finally, my left leg itches. These conditions have been in effect for 6 days. I can walk and even play volleyball, ride a bicycle, and mow the lawn.
