No cluster headache is a rebound headache. But you can get a regular headache as a result of taking analgesics for extended periods.
Cafergot supposedly causes rebounds also. I would say that if you take cafergot for a long time, your blood vessels are constricted. Stop taking it and the vessels "rebound" back to their desired diameter. They may overshoot this diameter, causing a headache until they correct and return to the desired state.
My take on rebounds.
