What is this feeling?

One of the challenges of OSA is analyzing and describing the symptoms I feel. The one that I notice the most now is like I am wearing a hat that is too tight - a slight, constant pressure over the top of my head, and sometimes around the back of the eyes. It doesn't really hurt, so I don't think of it as a headache. I don't think I could go to sleep now, so I would not describe it as sleepiness. I am not having any problem concentrating, so I would not call it fogginess. CPAP and Provigil don't seem to have any impact on this feeling. Anyone else know what I am talking about, and have a clue what I should try to get rid of this?

IF....IF you could "feel" hypertension, that is what that "pressure" would feel like (even though you cannot feel hypertension).

I had that head pressure feeling for over a year, I'd attempt to describe it to my doctor and he'd shake his head and say he didn't have a clue. Then my quack neuro said it was migraines, since she has been wrong like 9 out of 10 times she has attempted to diagnose anything with me prior to 2 strokes, I figured she was wrong with that guess too.

Did you ever figure out what the head pressure feeling is? Did it go away, and if so, what did you do to get rid of it?
I have tried to describe it to my doctors, but they don't seem interested.

I've had this feeling alot in the past, is it like this: intermittantly feels like I have a headband on. I would get many episodes of feeling tingly on my head. In fact just touching it would bring it on, and also just leaning over.
It felt like the muscles on my scalp were contracting. Do your symptoms feel anything like that?

At the time I had them, I was going through a horrible time in my life.......fibromyalgia, migraines, perimenopause, etc., etc. I even thought for awhile that I had Lyme disease, since so many people on a Lyme forum had these strange head neuro-type symptoms.
It finally all went away. I have it rarely now. In retrospect, I have no idea what it was. I think the approach I might take is that its a muscle thing. I would try to take those vitamins/minerals that might address the muscle issue, like calcium, magnesium and the B vitamins (especially sublingual B12).
I did have some sinus issues during that time and had 2 sinus surgeries.
I'm sorry, I don't know if you are male or female. If you are female around the age of perimenopause, then my guess would be that that was causing some funky symptoms.
Be sure to drink plenty of good water too.
I don't know about you, but those head sensations drove me nuts for awhile. I hope your's pass soon.
P.S.

It could be Psychological, Physical or Environmental or a combination.

A. Psychological - for instance, you where a hat that's a little too small for a while and after you take it off, you feel like you've still got a hat on. It's a fool the-senses-thing, not something whacked-out. Are you wearing your mask too tight at night? It may be a reaction to that.
B. Physical - It could be a migraine. My mother has migraines that induce the colorful pinwheels, but she has no pain. It's just another type of migraine. Perhaps you do have a sort of migraine. It could also be something else physical - perhaps you sleep funny and kink something in your neck that triggers nerves in your scalp.
C. Environmental - Lights of environmental things cause headaches. Try changing something in your environment and see if that makes a difference.

Things that induce headaches in some people include fluoride toothpaste, whitening toothpaste, tartar control toothpaste, shampoos with sodium laurel/laureth sulfates/sulfides (SLS, a surfactant), various smelly cleaning supplies, pesticides, food allergies. (Diary and gluten are common culprits.)

Start with the easy ones. Stop smoking. Try a different toothpaste without Fluoride, whiteners or tartar control. If that doesn't work, try a different shampoo that doesn't have SLS. It may take days or weeks to determine whether something could be a cause, but if you find a permanent solution simply by avoiding or not buying a particular product, wouldn't you live just a little happier?
