Hi, may I answer your health queries right now ? Please type your query here...twice now, once abt. a mo. ago and then two days ago, my 28 yr. old daughter , out of nowhere, developed a large "red" area, approx. 3" X 4" under the skin on her right inner thigh....just as though a large blood vessel broke and the blood came to the top of the skin. She has not bruised herself and it is in a very protected area. It hurts like it is a bruise and in a few days starts to get discolored like a bruise.
