Suggest Treatment For Headaches During Early Morning

I have been waking up with massve headaches everyday for the past 3 weeks and it is still continuing. I have had an MRI to check nothing is wrong with my brain and an angiogram to see if my blood vessels are normal. I have a really sore neck and I can't turn it all the way round and I am having pains in my back. I am wondering if i have something wrong with my back or neck that could be causing these headaches? The symptoms I get when I get a bad headache are extreme pressure behind my eyes, nausea, dizziness, shaking and aching in my neck. I wake up everyday as if I haven't slept and feel un refreshed. I sometimes wake in the night and cannot get back to sleep.
