Can swelling of the eyelids and sore throat only on one side be a symptom of hypersensitivity to an antibiotic?

It is difficult for an outsider to assess the situation on the basis of such a brief description. It is difficult to assess this without knowing your medical records. It is also difficult to propose a specific method of treatment without knowing your medical records. I encourage you to make an appointment with a dentist who will adjust the treatment according to your current clinical condition. If you have a history of hypersensitivity to penicillins or have a history of atopy, your risk of developing a hypersensitivity reaction to an antibiotic is higher. It may as well be progressive inflammation, especially if swelling and pressure occurred on the same side as the inflammation of the eight.
