I’ve posted in headache threads about migraines.
I think my 40 + years of occasional but intense migraines evolved into occipital neuralgia when I developed cervical neck pain a few years ago from arthritis - typical aging.
It lasted three years and then it gradually became milder but daily headaches each morning without so much occipital pain.
My neurologist said they were rebound headaches. I don’t think they were but she prescribed a course of steroids to break the cycle.
I recently found out about hypnic headaches and think I may have that type now but no diagnosis of that.
Sumatriptan at night prevents waking up with head pain but it’s not a good thing to do. I do drink coffee at night and in the morning.
My headaches have changed over the years. I don’t know if that is typical but I think it is possible because our bodies change as we age.
