Redness in lower legs when walking in cold weather. No breathlessness or pain. Any answer?

I am 65 years old appear to be in good health, I am not overweight and exercise regularly. I notice that when walking outside in cold weather my lower legs become red and sometimes give the appearance of small red dots on them. In that area I have very little hair but above that area I have lots of hair, also on the feet . I have no shortness of breath and no pain. I have also completed annual physicals which included stress tests with no apparent problem shown. Also, when I was young 20 s I recall that when being out in the sun my lower legs sometimes would develop small red dots and remain for a day or so. Any answer?

Thanks for posting your query.
with the available described symptoms, there appears to be high possibility of formation of purpura (elevated blood collection coming out from capillaries) or cold induced skin allergies.
You should consult with internal medicine specialist / general surgeon and should go for thorough clinical examination.
Palpation of peripheral artery pulsation is mandatory.
Decreased blood supply to extremities may cause shiny skin with loss of hairs.
You should also go for clotting time, bleeding time, complete blood count, and prothrombin time.
Treatment depends on exact diagnosis.
Take care,
