Hi, two days ago I went to dentist and had oral thrush, canker sore and an ulcer. They gave me magic mouthwash that had an ingredient that was for parasites. After using it a few times I noticed an big buldge on my chin. I squeezed it atleast 20 times and lots of fluid came out. Then it moved. I was able to squeeze fluid out of my entire chin. My hands, I guess the joints are extremely painful. Any clue what this might be?
