I got mumps 2 years ago now I'm 30. But my tonsils get swelled and they hurt if i'm catching cold and cough or eat anything that is sour. Besides that i sometimes also have pain in my left ear pinna ...
Oh dear, I think you should go see your regular doctor or maybe an ear, nose & throat specialist. You might have an infection that hasn't gone away or maybe you even need to have your tonsils out?
