I'm no doctor, but I will share my experiences with you.. I'm 41, pretty much athletic my entire life. My legs (knees in particular) always turn a bright red (purplish, almost sunburned looking)) after a run or anything where I push myself.
hello! i forget to say that my feet also gets red and when i take a shower with hot water my hands get even more red ( deep red). And also when i excercise ( cause i am an athletic guy ) the same happens. :)
Hi!
One possibility is faulty valves in the deep veins preventing all the blood poor in oxygen from going back to the heart. Once you raise the arm, the blood flows down along the gravity. A color dopplar of the arm blood vessels can help diagnose this.
The second possibility is compression of blood vessel due to some cause. Do discuss this with your doctor and get yourself examined. Take care!
