My question is about my friend, 62 yrs., and her skin breaks easily and bleeds. She bumps her arm on the edge of a cabinet opening and she bleeds. Begins as flowing bleeding then after getting it to stop it will ooze for a few more hours. Is this something that needs to be addressed by her doctor? Additionally, the other night she felt a itch on the inside of her knee. When she scratched the area, a piece of skin the size of a large pea in circumference and about 1/16th of an inch thick came off. It did not bleed but. She put neosporine on it and a band-aid. The next day no scab had formed and it never bled. So then she left it exposed to the air overnight and it did form a scab over about half of the area. We do not know what to make of these events.
