RightOutOfTheBlk&Blu: Yes, unless your thumb got banged by an invisible painless hammer, you should see a doctor. Of course, a lot more needs to be known about you, like any chronic illness, what medications you take,what types of activities or work you engage in, etc. But at your age a painful blue (or pale) thumb that just comes out of nowhere is concerning and you should make sure your heart and blood vessels are OK
