I am having a lot of unusual bruises mostly on my forearms. They are unusual because they don t react like normal bruises. They don t change color or heal from the outside in. They are a very dark red and the skin returns to normal from the inside out resulting in a red ring around where the bruise was. My skin is also very tender and it takes very little for a skin tear where a flap of skin the size of a penny or a nickle will happen from the slightest bump against anything. I can put the skin back over the wound and it reconnects and heals normaly. Do you know what is causing this?
