i'm 14 and have this crackling noise in the back of the head near the neck. I only get it about three times a week. I get headaches alot but i have taken cod liver oil and that has helped heaps, get less headaches and they are not bad. Can these headaches be related? I get headaches at the back of the head as well but not near the neck. But is this crackling noise serious? I have read some other peoples questions about what sounds like the same thing as what i have, and that it can be related to arthritis. But aren't i too young to get arthritis? I have no idea and am scared that it can be serious. Please help me.
