Based on the symptoms you are describing, it is extremely unlikely that the previous CT scan missed a brain tumor. Occasionally a CT scan can miss a brain tumor if it is very small.
However, there are dozens of possible causes of head and neck pain, and it is unusual for a brain tumor to only cause head and neck pain without other signs or symptoms. Now, add to that the fact that you already had a CT of the head which showed no tumor. I would not worry about a brain tumor unless additional symptoms develop such as seizure, paralysis, loss of feeling in the extremities, vision loss, etc.
