I have swollen tonsils on the right, I don't know from how many days, since there is no any other symptoms. I had sore throat before one month that time I have noticed both the tonsils were increased in their sizes. Also I have hypothyroidism and on medication for
B12 deficiency. As of now I don't have any significant other symptoms, there is sore throat sometimes in the morning but it goes by itself. What would be the reason behind one swollen tonsils?
