So A While Back I Popped A Zit On My

so a while back i popped a zit on my back near my shoulder and like all zits it sprayed a little puss and bled a little. few days go by and it starts to look like there is dried blood under the skin and i squeezed at it again and it shot blood and now there is a fair sized hole sitting there with the same dried blood looking hole even though its not bleeding
