Hi, my knuckles have turned red on both hands . the same thing happens on the palms of my hands but to a lesser degree. The redness increases whenever i walk for a little while. There is no noticeable swelling and although I wouldn t call it pain , there is a tightness and uncomfortable feeling in my hands after a walk. I am 34, 6 2, 185 with no diagnosed medical issues at the moment ( had ITP in my early twenties but no symptoms of that in 9 years).
