What is this white thing in my mouth

[gijoe112353]

I noticed this white thing at the back of my mouth. It is horizontally center with the uvula but vertically underneath it. It would appear to be like some kind of mass, rather than an ulcer on the back/wall of my mouth as shining a light against it produces a shadow.  It also appears to have blood vessels.  In the past couple days I have noticed a slight pain when I swallow and can feel something back there.

I have taken a photo of it which can be seen at the link below (NOTE this is a picture of the inside of my mouth, if this is something you may find offensive please do not click on the link). In the picture it is to the left of the uvula because of the angle the photo was taken on, but it is actually center to the uvula.

Any idea what this is?

You really should see your dentist or doctor about this.
