You should be evaluated for obstructive sleep apnea and other secondary causes of headache. Especially if you get up in the middle of the night with a headache, getting an mri scan would be justified.
Seek the care of a good neurologist near you. I wish you the best and hope your problems are resolved soon.
Sincerely,
Siddharth.
