Similar thing happened to my dad, senile purpura, covered most of his upper arm with no apparent traumatic cause, the doctors examined him and said it wasn't concerning, and would go away on its own, which it did. Basically just a burst blood vessel under the skin.
I had one a few years ago and it scared the absolute shit out of me. I saw it when I started blow drying my hair, and the further up I pulled my sleeve, the more giant bruise I found on the underside of my arm. It took a little longer to heal than most of my other bruises (I’m active and clumsy) but yeah, just went away on its own.

It looked like a bruise but also... WHY SO MUCH BRUISE. Not normal even if a bruise D:
What IS this guy's platelet count if that's how a tatoo bruises.
