I have a dark red patch on both of my ankles which seems to be spreading up my legs. It started around 2 years ago as small red dots under the skin but it's now advanced to a large area. Sometimes the patches are more red than others, usually if I've been on my feet all day at work. There's no itching of discomfort but they look quite bad. I've seen 3 dermatologists but no cure. I used hydrocortisone cream which really helped but they came back once I stopped using it. Can anyone help please before it covers all my lower leg! Thank you. I've attached pics.
