A detailed history and examination is necessary for appropriate diagnosis and management of your condition. A cyst on the tongue presents as a lump under the surface of the tongue. A cyst on the tongue can cause difficulties with swallowing or breathing if they protrude from the surface and grow too large. A cyst on the tongue can become infected .Other possibility is a condition called transient lingual papillitis.This condition is limited to the upper surface of the tongue, affecting few tiny bumps on the tongue when these bumps become red or white and are quite tender for few days. If the bump is under the tongue another possibility is that of a mandibular torus. It represents extra bone that most often occurs on the tongue-side of the lower jaw or on the roof of the mouth. A clinical examination is necessary. You should get yourself reviewed by an ENT specialist. Hope it helps.
Best luck ad regards!
This lump is actually inside my tongue and can only be felt from the underneath. Some times it feels harder then eventually goes back to feeling soft but is always there. Its in my tongue not at all visible from the outside. And its just about an inch back from the tip. You can only feel it from the under part of my tongue and no other way..
While I don't pretend to be a doctor or any type of practitioner, I had something similar years ago. I woke up with a very sore tongue and upon pressing it between teeth and up on roof of mouth, I could feel a knot or bump. I didn't have any other symptoms and had a good night's sleep, nothing out of the ordinary so this bump, which felt huge inside my mouth, scared me, lol. I got up and tried to view it in the mirror and felt all around with my fingers. It was in the middle (between top and bottom) of my tongue and it really hurt when i pressed it between my fingers but my tongue appeared normal on sight. Needless to say, I made appointment to see my doc that day and because there was no fever or other symptoms, everything ruled out. He explained to me that there are lymph nodes in your tongue and that this was most likely just a swollen lymph node. He said these often swell during illness and can swell for no apparent reason, but usually something is probably being battled by the body on our behalf and we would never need to know it unless our immune system couldn't handle it alone and other symptoms, tests etc. happened to confirm. Warm rag and analgesic eased the soreness and if i remember correctly it was back to normal in just a day or so. I notice my lymph nodes in my neck are sometimes swollen and a little tender (nothing like the one in my tongue) and I'm not feeling sick. They can swell over something in your shampoo, laundry detergent, deodorant, etc. and you not realize you have mild allergies that your immune system is constantly fighting and winning the battle for your body. This happens for each of us, among many other things, in the course of each day.
So, I hope that this is the case for you, especially since you've noticed it to some degree for several years. It would make sense.
I hope all is well for you very soon.
