I feel HORRID today. As bad as I did back in November when I sustained my most recent concussion. Possibly worse. I haven't felt this poor in months. All ov a sudden. Out of the blue. My head is throbbing and I cant even remember what I had for breakfast this morning

The pillow I swtiched to last night is very, very firm. Like almost solid upon contact, then it sinks inward. I'm really afraid that I came down onto it too hard in my sleep or something. Is this possible? Can you concuss yourself from a firm surface like this? It's a really heavy pillow. I can't believe I thought that was a good idea. I dont understand whats wrong with me today.
