Does anyone else ever get this feeling like their body, and especially their head, is expanding or swelling? I get it when I'm laying in bed sometimes. I have it quite bad today. It's like my head is getting larger and larger, and I have the feeling of my tongue swelling up or all lumped up and too big for my mouth. Really my whole body feels like it's getting bigger and bigger. It's really strange and hard to explain. It doesn't hurt or anything but it is kind of uncomfortable.
