I have Brownish-red color spots on my legs

It started about a year and a half ago. It is on the top of my foot and all over my lower legs really bad. It is to the point when I stand for a long period of time my legs sometimes go numb, or like there is hardly any blood flow. My ankles have been hurting. I started to sleep with my legs proped up thinking that would help. Sometimes it works and other times it really don't. I just noticed that it is starting to spread up to my upper legs, but it is not spreading fast at all like hives. It is taking days to weeks to get there. I have no clue what this is. I have had two C-sections. Can you please help understand what this is?

Sincerley,
