When I sleep on one side of my head the next morning I get a headache on the left side of my head ( area of impact ) immediately after waking up and it does not matter which side of my head I sleep on.
If I sleep with a straight head, I won't usually get a headache unless studying hard for an exam or something.
Is this common?

These headaches started three months after my concussion. are they concussion headaches?

Is your neck sore also? It could be a sleeping /positional thing.
I'd try to sleep straight as much as possible and see how it goes.

No, I don't have any neck pain. It's just left side of my head.

I too get the same thing. I had a stoke about 5 years ago and I get this headache ever since. It's when I sleep on my left side. I do think brain damage has something to do with it. I did lose some of my speech and balance but I have got that back, well 95% of it.

Try sleeping on the opposite side.

Only when I sleep straight I don't get headaches.

You don't need to experience any neck pain to still have a neck issue. You can try sleeping with a pillow thick enough to hold your head and neck straight when you are on your side. If this resolves your headaches, you have found your problem.

I had a similar problem but instead of headaches, I would stop breathing during my sleep. It took months of sleeping on my back with my head and neck straight to start to strengthen my neck so I could occasionally sleep on my side. It took a year or so to get reliable stability in my neck.

This may support the theory that concussion disturbs the brains blood flow. I think this will be temporary in the case of PCS but linger in the case of stroke.
