What is the size of lump? Is it painful, red and tender? Is the skin over it can be moved or is stuck to the lump? Can you move the lump all over? How does it feels, fluid filled, soft, firm, hard? Can you compress it fully that it disappears?
Thank you for your prompt response Dr. Arun. I feel much better knowing that I am talking with someone of adequate knowledge concerning my issue. As far as the size of my lump, it is about the size of a pea and it does not move with my skin; it's stationary on what it seems to be my skull. It isn't red or discolored in any way and is not tender, just annoying when touched. It's actually a solid, however, one morning when I had a really bad heachache, it felt a little mushy. But that was the only time. Right now, just as it always had been before, it is a hard substance. When I press it, it doesn't disappear, but rather feels pushed in. Thank you again Dr. Arun.
Following possibilities would be considered;
1) A dermoid cyst
2) An osteoma
3) A sebaceous cyst
All of these swellings are benign swelling and are not harmful or worrying.

Tumor of the brain never come outside. This itself being tumor would be a very rare (almost unlikely) possibility. The headaches can be because of your worry or can be migraine, which can present in the ways you had described.
