I have a line of blood under my skin from a blood pressure test....?

Question

I got my blood pressure tested today - I was in a room with the machine that squeezed and unsqueezed my arm 6 times. It was incredibly tight and kind of hurt - there was no doctor in the room. Now I have a line (about 2 inches long) of dark spots of blood on my arm. Is that normal?

Answer 1

It isn't supposed to do it,

but it isn't out of the realm of normality

what happened is the pressure cuff had a difficult time

locating your pulse to signal the cuff to start releasing

and caused a slight bruise (raised blood to the surface)
