Headcahes caused by brain tumors are generally new headaches and yes they do get worse by bending over, accompanied with slurring of speech, seizures, muscle weakness. The neurological examination is always abnormal in patients with brain tumors.Since you have had these headaches for many years now and do not have any other symptoms, with normal MRI you need not worry. But if it is giving you sleepless nights please get yourself evaluated by a neurologist.Good luck!
