During my childhood I accidentally found a bump on my scalp under skin then, we went for a doctor and he told it is normal if you have no symptoms but after 10 to 15 years I am little afraid and want to know is it normal or should I see a doctor?? Bump size is almost same it has not increased much in 10-15 years. Bump is under skin and skin is normal in colour and hairs are growing over it. Bump is painless No other symptoms Roughly size of bump 1- 1.5cm Bump is hard
