can CH's maintain minimal discomfort between attack's? Without going through too much medical history, I suffered an debilitating headache last friday, sunday, and last night. In researching my symptoms, I am very concerned I am experiencing cluster headaches. After my headache last night (mine have been around 6pm and lasting for an hour or two), I woke up this morning with a minor headache, but not around my eye. It is located on the same side but in top to rear of my head (where my headaches progress to after starting out around my eye). It is almost feels like pressure or a nerve throbbing or something. Has any one else experienced this? Or between attacks does all pain or pressure completely subside?
