question: Hi...i am 6'2 ,180 pounds and 25 yrs old,I dislocated hand a few years, that's basically the only history I have..... i was laying down with my head resting on a something in my room, and now their is a lump on the back of my head on the right side, it's been their for almost two weeks now and it hurts alot when I touch it and if I should hold my head down for a short period of time and then hold it up straight I would have a strong pain rushing in that area where the lump is and it would go down the back of my head, down to my neck, even when I lay down and the get up to a standing position I would feel this tension where the lump is and it feels like I am getting a headache.... Could u please tell me what this can be, thank u.
