Symptoms of tonsillitis include a sore throat, red or swollen tonsils, difficulty swallowing, fever, headache, among other aches and pains. Sometimes, tonsillitis causes you to lose your voice. If you have symptoms of tonsillitis, see a doctor to have a rapid strep test. You will need antibiotics if you have strep throat. If your tonsils are very swollen, you may receive a steroid shot.
