About 2 days ago I noticed an unexplained bruise on my arm, on the top area (pouch) above the elbow area. It seems to be in the same area as a vein and I kind of feel the vein was damaged somewhat (hence the bruise?). The middle of the bruise is almost a darker straight line, and on either side of the line is a darkened, but lighter shaded area. It does not hurt. I do have the tendency to sleep on this area. And alot of times when I am sitting in this chair, I wrap my arm on the top of the chair which applies pressure to the area. But I don't remember any episode that would cause such a visible bruise, so I am wondering if everybody has episodes of unexplained bruises once in awhile, and if so what cream can be applied to lessen the look. Also, if this sounds abnormal, what could it be? Again, it does not hurt, itch or cause any discomfort. It's just unsightly. Thanks.
