i don't know what these bumps are but i suggest you see a medical professional for a diagnosis. in general it's a bad idea to squeeze or pop skin bumps or lesions because when you do this you create a hole in the skin that infectious bacteria can enter through. this can lead to an infection loss of skin scarring etc. lumps on the scalp aren't exactly uncommon. it's possible these are cysts or lipomas. only a health care provider can say for sure. all the best to you!
i have bumps on my head that act like zits but are harder to pop. there is a hard white piece that comes out. what is it. so these bumps that are on my head are hard to pop but if i keep messing with them they eventually pop there are hard white pieces that come out. sometimes they act like zits and the whitish puss stuff comes out like any other zit. but anyways the hard white piece comes out and i had thought they were calcium deposits. the last one that i had popped a small round hard piece came out that looked like an onion. that it had layers of "skin" and was probably mush on the inside. what is it?
