Internal Medicine

Swollen tonsils, medically known as tonsillitis, typically cause a sore throat, pain or difficulty swallowing, and swelling at the back of the throat. Additional symptoms may include ear pain, a muffled or scratchy voice, bad breath, fever, or a sensation of fullness in the throat. In some cases, white or yellow patches may appear on the tonsils.

Because swollen tonsils can result from viral infections, bacterial infections like strep throat, or other underlying conditions, identifying the cause matters for proper treatment. The fastest way to understand your symptoms and know what steps to take next is to complete a free, instant, online symptom check—it's private, doctor-developed, and can help you decide whether home care, a doctor visit, or urgent care is right for you.

Explanation

Swollen tonsils, also known as tonsillitis, can lead to several uncomfortable symptoms. A common sign is a sore throat, which can make swallowing painful. Sometimes, this can be accompanied by a sensation of fullness or pressure in the throat area. In some cases, individuals might experience ear pain because the nerves in the throat and ear are connected.

Other Possible Symptoms:

Lingual Tonsillitis: When the lingual tonsils are swollen, it can cause a sore throat and discomfort in the throat area.
Unilateral Tonsillar Enlargement: This is when one tonsil is larger than the other and can sometimes indicate more serious conditions like lymphoma, which might need further medical evaluation.
Tonsillolithiasis: This condition involves the formation of small stones in the tonsils, which can lead to orofacial pain, a discomfort that affects the face and mouth area.
