I have a lot (A LOT) of hay fever type allergies (indoor and outdoor). I would get rid of your pillow first. I need to get new ones (As mentioned prev.) at least once or twice per year, or else I wake up in the night with symptoms like you express. And yes, bedding must be washed a bit more frequently. I get away with bi-weekly, but I know weekly would be better. If you get a new pillow with clean bedding, and still have the problem, then I would recommend moving to further investigation (ie. see a Dr., try an OTC anti-histamine before going to bed etc.)
But I truly suspect your pillow. It still amazes me the difference I see with new pillows!
