Hello, I had my tonsils removed over a year ago. Since then I ve been getting little blister like things often on the back of my throat where my tonsils used to be. The doctors said it was remains of tonsil. However it feels though there is food jammed and if I apply pressure to the lump it pops. It appears on both sides of my throat. It hurts when the lump is there. When the lump isn t there it doesn t hurt. No bleeding at all.
