Dear Tacia ureta I am sure your Doctor is right you have got tonsilitis
. You are getting problem with your (R)ear is due to bolockage of a tube known as pharingo tymphanic tubes which connect throat with ears.It will settle down. I can suggest an old fashoned remedy for sore throat
. take some warm water (tumbler full) and add couple of soluble aspirin
tablets to dissolve and do the girgle twice daily. Kindest regards.
