Swollen forehead or brow bone? (Photo)

hello i don`t know why my forehead is swollen if it is a brow bone is there any other way to reduce instead of surgery, its really irritating me, i observed it 1 month ago i don`t since when i had this problem i checked my previous photos when i was 18 there was no swelling i am 20 now, i also smoke and hear music in my earphones on too loud music is it due to that? and the swelling is like sometimes it disappears for some hours and comes back .thank you very much in advance
