I have been having sever headaches that seem to start from dreaming they wake me up at night and cannot get back to sleep cause of the pain?

See below: Few disorders can present as such, one of which is sleep apnea (as you wake up from rem sleep w/ headaches) this is especially true if you snore, gasp or choke for breath at night, have a dry mouth, night time reflux, ;/or daytime sleepiness. In that case, an eval. By a sleep doctor is recommended. Otherwise if you have other symptoms, a neurologist can eval. You for other causes of your headaches.
