I am a 60 yr old widow, with no health issues, weigh 126#. Last night I noticed a very dark large reddish-purple bruise on my upper inner thigh, about 2 from the crotch area. I bruise easily, but it s just a very odd place to get a bruise. It almost looks like it s bleeding. I don t recall any injury or anything that may have caused it. It doesn t hurt, doesn t itch. Any reason to be concerned???
