 [ Symptoms ] just had 3 root canals at the dentist now i have lots of pain [ Disease ] i do not know what these bumps are but i suggest you see a medical professional for a diagnosis in general it is 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 are not exactly uncommon it is possible these are cysts or lipomas only a health care provider can say for sure all the best to you
