What Causes Swelling And Warm Sensation In The Feet And Ankle?

Hello.... I ve been having some fet and ankle swellng, starting on my left leg, sometimes it gets red and feels warm and there is also a dark color ( looks like a bruise) on the ankle like right below the ankle bone and my leg at times also feels like a needle stick and just this week I started to notice it happening on my right ankle and also felt like right below my right knee , like a burn and it literally tore off some skin, like as if was rubbed, the strangest thing, thought I got bit by a bug but I was watching TV, did not see anything.... did some reseraching, is it possible I may have peripheral vascular disease. I am diabetic ( type II) and do have a history of heart disease,
