It's not a tumor!
I haven't had one in so long I sat at me desk in denial until I had to run to the bathroom and throw up from the pain. I asked to leave and walked home throwing up on the sidewalks of Seattle the entire way. I ran in my house and laid in my dark closet with a pillow over my head for most of the evening. At about the same time today it happened again! If I didn't feel so good otherwise my first intuition would be stress? I don't know, hopefully it's just a once in every ten year or so anomaly because it SUPER hurts BAD!
