Red rash behind knee; blood vessel?

Specializes in Phlebology

Doubtful.: A rash probably is not a blood vessel unless you have a group of spider veins in that area which would give the appearance of spider legs. Varicose veins would be raised, blue and grape-like in appearance. A red rash doesn't sound like veins. You should see a vein specialist for an evaluation.
