I have different size spots that are filled with blood on my chest (mostly on breasts) and down to my stomach around my belly button. I've accidentally scratched the one beside my belly button and it's bled for hours & soaked 3- 4' gauze pads. They don't itch, just scratch them when dressing or bathing in a hurry. What could they be? Have lots on my chest in different sizes but they seem to grow. Thanks for any input. I have systemic lupus.
