Im thinking this probably isnt to do with my ME/CFS but about 6 weeks ago I got a dark skin patch which looked like a bruise... hyperpigmentation. Thing is it cant be a bruise as its still there and now has very dry looking skin in that place but still is dark like a bruise. Its about 1 inch by 1.5 inches in size on a skin crease area (top of my foot). Could this be some kind of strange eczema? (Ive never heard of eczema looking like bruises.. my daughter used to get eczema). It does occassionally have a slight itch to it now that the skin in that area has also gone dry. What would cause a dark patch of skin? (It went dark before it got the dryness in that area) It dont look thou like Staph (I once had staph in my leg which went inflammed and gooy and had spreading pitch black colour under my skin).
