I have a patch of blue skin at back of armpit on right arm. Looks like the same colour as veins. Been like this for 7+ years. Any idea what it is?

it depends on the size and the color and if its changing at all , need to be checked by a doctor esp its you noticed just 7 years ago .
it might be a blue colored mole but it can be somethings else depending on the exam
