Bit my tongue accidentally yesterday. And now it hurts when moving the tongue back. Could it be due to that or something else? Please help!

Your Tongue. The tongue is a highly sensitive part of the oral cavity that unfortunately or fortunately lets you know when there is something different in the mouth. Movement of your tongue against your teeth, especially if along the side of your tongue can be quite uncomfortable. There are some OTC rinses and/or meds that can be used to help numb the area.
