My husband have a big bump on his head and it comes out it different location on the head. Sometime when you squeeze it yellow puss comes out. He went to the doctor n they said its an infection and they gave him antibiotic and it left but a really bigger one came back....he pops it flat but then a few hour later its big again...its like when u pop a pimple n it come back but way bigger. Can it be the clippers he cut his hair with because I cut my brothers hair and it was full of pop pimples and dry skin, but I cleaned it...but after I cut his hair my husband started getting these things. what can this be we scare its cancer or something
Hello there! That fast thing is hardly a cancer. It looks to me some sebaceous cyst which is infected. All it need is incision and Chat Doctor.  Seek a general surgeon help and modify the hair hygiene. Your issue will resolve. Good Lucks Khan
