I have lots of small orange bumps on the back of my throat. The very back (not on the tounge) and a few on the roof of my mouth. What couldn't be?

Call your dentist. Please make an appointment with your dentist or physician. There is no way of diagnosing your specific condition over the internet. Your dentist or physician will do a clinical exam, and make a recommendation. Take care..
Needs to be seen. Unfortunately we can't accurately diagnose what you see without actually seeing it for ourselves in person. I suggest that you see your physician for an accurate diagnosis.
