A member asked:

What causes the red rash that appears on the back of my calves after a long walk? is it something to be concerned about?

A doctor has provided 1 answer

Not really: Do you mean in the back of your knees or calf? If it is on your calf, and goes away your probably fine. These with us doctors anyone who says the word "calves" gets a venous doppler because of possibility of blood clot. If you are mobile and walking a lot, blood clots are not likely. Sometimes you can get a rash from heat, fungus, some sort of exposure to an allergen.
