ive been advised botox and fillers to even my forehead out coz the doctor isnt concerned
ive had the bump for 5 years and no pain so i dont think its the same as ur friend @ray535
i got a friend who has a tumor on the top of his head, he got pain on his body part he could hardly move but manage to go for a surgery. a tumor.
in your case you should go to an emergency to have it checked before it happened.
I can see that this would be upsetting for you, even if harmless. Please go find a doctor who is symathetic and can suggest ways of getting rid of it asap. -Blu
