owwww my neck hurts

Well, I thought that I was going to be heading off to work today, but when the alarm rang this morning I rolled over to turn it off and when I got 2/3 of the way over and was reaching out my hand I suddenly felt a sharp pain shoot up from my neck to the top of my head and down my side to my hip, My neck is now locked, I took some Tylenol even tho I'm not supposed to because of my ulcer and I'm using heat even tho it;s hot in here this AM. And it's hard typing with one hand so I'll stop now.
