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.
