Skin Hanging Under Tongue, Affected When Swallowing, Painful. Concerned
Thanks for posting your query.
First, I would like to know the duration i.e.: since when have you noticed the piece of skin hanging under your tongue, did it develop after any particular incident and also the size and color of the same?
The pain you experienced while trying to pull it off is due to the nerves and vessels as the piece is attached to the underlying mucosa.
Assuming it is just a harmless piece of flesh or loose mucosa but pains or irritates when it gets stretched, then you need to go to a dentist preferably an oral surgeon and get it excised. It is a minor procedure done under local anesthesia with no side effects. Sometimes a biopsy of the excised tissue may be advised.
I would recommend you to visit your dentist for a clinical examination and accurate conclusion.
I would be happy to answer any further questions you have.
Regards
