Granulocytosis as a result of her thyroid disorder: Granulocytosis is not typically associated with hyperthyroidism.

Thyroid storm: While thyroid storm can cause fever, it's unlikely to cause a sore throat and would more commonly present with symptoms like palpitations, increased body temperature, and changes in mental status.

Thyroid cancer: This would not typically present with fever and sore throat. A thyroid nodule, hoarseness, or trouble swallowing would be more common.

Thyroiditis: While this could potentially be responsible for fever, it's an unlikely cause when a patient is already being treated for hyperthyroidism, and wouldn't explain the patient's sore throat.
