Hello, Your symptoms could be from either or both. Did your doctor diagnosis strep? You should start your amoxicillin and complete the prescription as directed. This will offer relief in both instances. Take anti-inflammatory medication such as acetaminophen or ibuprofen. Benadryl, an antihistamine, helps control inflammation and reduce swelling as well. Rinse with warm salt water. You may have bitten your cheek with the swelling and sore spot. Keep hydrated. Avoid vitamin deficiencies and maintain good nutrition. Practice good oral hygiene. Schedule an exam with your dentist or oral surgeon to evaluate the wisdom tooth. You may need an extraction. Infections can spread and have serious consequences. Corticosteroids may be prescribed for a great amount of inflammation. A chlorhexdine gluconate rinse is often recommended and can help with healing sore spots. Avoid irritants such as smoking, alcohol, spicy and acidic foods. Thank you for your inquiry.
