I'm feeling really anxious about this odd thing in the back of my throat. I managed to get a picture of it but I'm not quite sure if I can share it here or not. It looks like a small off-white square way back there behind my tongue. The wider I open my mouth, the more visible it gets, and it seems to bob up and down. Should I be worried? Any idea what this could be?
Based on your description, it sounds like you may have a case of tonsilloliths, also known as tonsil stones. These are small, off-white deposits that can form in the crevices of your tonsils. They can sometimes cause discomfort or a sensation of something being stuck in your throat. To help alleviate the symptoms and prevent further tonsil stone formation, you can try gargling with warm salt water or using a water flosser to gently dislodge the stones. In some cases, if the tonsil stones are persistent or causing significant issues, a doctor may recommend removal of the tonsils. In the meantime, you can also try using a mouthwash containing chlorhexidine or hydrogen peroxide to help reduce bacteria in the mouth and prevent the formation of new tonsil stones.
