Swollen or Red Tonsils
Swollen or red tonsils are a common sign of throat infection or inflammation. The tonsils, located at the back of the throat, act as part of the immune system's first line of defense. When they become infected or inflamed, they can swell, turn red, and cause significant discomfort.
⚠️ Seek Emergency Care For:
- Difficulty breathing or swallowing
- Drooling or inability to swallow saliva
- High fever over 103°F (39.4°C)
- Severe neck stiffness
- Muffled or 'hot potato' voice
- One-sided severe swelling
- Signs of dehydration
- Difficulty opening mouth (trismus)
Definition and Overview
Tonsil inflammation can result from viral or bacterial infections, with strep throat being one of the most common bacterial causes. The condition can affect people of all ages but is particularly common in children and teenagers. Symptoms may range from mild discomfort to severe pain that interferes with eating and drinking.
While many cases of swollen tonsils resolve with home care, some require antibiotic treatment or, in chronic cases, surgical removal (tonsillectomy). Recognizing the signs of serious infection and knowing when to seek medical care is important for preventing complications.
