Tonsil stones?

I think I may have one. My throat has bothered me for a couple weeks. Not enough to go to the dr but uncomfortable and scratchy. I constantly feel like I need to drink water. I thought it was just allergies.

It feels like something may be stuck back there... like that constant feeling of mucus caught in your throat but in one spot. So I used the flashlight on my phone and took a look... it looks like a white lump behind my one tonsil. I think it may be a tonsil stone. I’ve never had one that I knew of before.

If you have had one.. did it go away on its own? How long did it take? Or did you have to go to a doctor and have it removed?
