The tongue may be slightly painful due to inflamed lingual papillae. This is usually caused by physical trauma to the tongue. Patients may experience symptoms such as swelling and bleeding of the tongue, along with a stinging pain during eating. It could also be oral ulcers, commonly resulting from frequent consumption of spicy or irritating foods, leading to ulceration and pain on the tongue.
