I know we tend to think of all the bad and serious things that might be wrong, but in doing so we in danger of overlooking the simple ones, of which there are probably many more, and are much more common as pain instigators.
It sounds to me like a simple case of very tight muscles, as you suggest.
Tight and knotted back muscles can't relax and lengthen as they should, so they get sore, and pull down on the neck muscles. They then hurt too.
These then pull on the scalp muscles, making the head sore as well.
So you can have a variety of very strong pain in your back, shoulders, arms, neck and head, even the eyes, just from muscle problems.
I know, I have it bad.
The remedy for me is regular remedial massages. Pain went immediately. Still comes back if I overdo it, but much, much less and more easily controlled.
My new pain doctor diagnosed this problem, and he was 100% correct.

I also do a stretch and exercise routine for 30m most days.

Yes. I do believe that tense muscles play into this. I also still have this darn nasal drip.. and it kept me up half the night. So perhaps tension, worry, stress and a sinus issue.. oh who knows??LOL. I do know they have not called me yet about my MRI and I am anxious as heck. I'd like to know what they saw or did not see. Thanks for your reply. I just hope it's not an anyerisum... that really scares me. I did have an MRA under a year ago, and that was nice and clear.. none found. Do you think one could have developed? I have NO family history of them.

I understand how worrisome this is. I used to worry about an aneurysm too, but my sister died from one at the age of 37. It was about thirty years ago when the surgery was much more invasive, and she didn't survive it.

Aneurysm headaches are very severe from what I recall, and tend to get worse if you lie down. I remember that my sister's was so bad she had to go to the ER for pain meds. They gave her some and sent her home but it didn't help, so she went back the next day with even worse pain and they finally figured out what the problem was and she was transferred to a neurology hospital out of town.

Just got the MRI results and it came back perfect very normal, no questionable findings. So, I guess I can relax a bit now and figure out how to manage my headaches and clear up this nasal drip.

Has anybody mentioned cluster headaches?
