Swelling under the tongue its hardish when i push on it.. sometimes it seems to get a burn/tingle feeling. anything i could do?

Yes!: See a dentist, preferably an oral and maxillofacial surgeon, for diagnosis and treatment. Can be anything from blocked salivary duct to a neoplasm. Rx requires that you see a professional. You can't fix this with a mouthwash, salve, ointment, or any other otcproduct. You need an expert.

I'd recommend you: See your dr to be sure we don't miss treating an abscess or infection. Or it could just be a cyst or salivary gland inflammation. Take care!

Hard swelling mouth: This is very likely a swollen major salivary gland. The gland produces saliva releases it into the mouth through tubes called ducts. If these become crushed from eating something hard the fluid backs up causing the gland to swell. In the floor of the mouth these are called ranula cysts. Small ones are mucoceles.Get an eval with an oral surgeon/ent for a check for this and other things.

Yes, get it checked: If it doesn't go away by itself in a day or two you need to get it checked out.

Absolutely: You must see a professional to diagnose what you are describing. It could be many things, almost all of which require some form of treatment. I would recommend seeing your general dentist or an oral surgeon. Early treatment prior to a flareup of symptoms is always a smart idea.

Many conditions: Cause swelling under the tongue. It could be related to obstruction of the salivary glands, a tumor, a dental infection. Infections tend to have pain. If you are having trouble swallowing see a physician or oral surgeon right away. If not, still a good idea to be examined by the doctor.
