I Have Been Having This Almost Uncontrollable Urge To Stretch.

I have been having this almost uncontrollable urge to stretch. It hit me today as I was walking into a room and when I stretched I immediately had a horrible pain in the top of my head. It became a pounding headache where I felt like I could feel my heart beat through the throbbing in my head. I also am running a temp of 101. I cant imagine what this could be. Never happened before...just the stretching.
