thank you. that makes me feel better
Hello,
It is very difficult to say anything without examination,but from your description,it looks like you are mentioning about the ducts of the salivary glands which open under the tongue. The sublingual and submaxillary (also called the submandibular) glands empty into the mouth through ducts under the tongue. The two largest ducts are in the center just in front of the attachment of the lingual frenum and are called Wharton's Ducts.These are normal anatomy of the undersurface of the tongue.
Hope this information helps.Take care and pls do keep me posted if you have any additional queries.
