If you have been experiencing sharp pain in your ear while swallowing and do not have any other symptoms like a cold, it is important to consult a doctor. This could potentially be an infection inside your ear, which may require antibiotics. It is best to seek medical advice to determine the exact cause of your pain and to receive proper treatment. Avoid self-medicating with over-the-counter drugs as this may not address the underlying issue. Make sure to consult a healthcare professional as soon as possible for appropriate care.
