Anyone feel major pressure in their face/head when laying sideways on a pillow?

I've been having this issue more often than not recently, and I honestly don't know if it's IIH related but it feels like my head is about to explode, and if I lay my head/face sideways onto a pillow or any surface really, it creates more pressure and therefore more pain. I don't know if this is a sinus issue or an IIH issue or what have you, so I thought I'd ask here if anyone has had a shared experience. Sorry if my post seems a bit jumbled, I haven't been sleeping much lately.
