It seems like I have the same thing. Under the right side of my tongue I have this "bubble" that will swell so big that you can, like, see through it, almost & it has like a division down the middle. It is, as though, there are two or one that has swelled into another part. Like a cell that is multiplying into halves.
My boyfriend says it looks like a blood blister but I don't really see blood or see it bloody inside, a lil veiny maybe.
When it is not swollen & "bubbled" up, it almost goes all the way down to normal but I can see a couple of white spots.
Some months ago I had a molar (2nd to last tooth on the r.side) pulled out and since then I have bitten my tongue (UNDER my tongue)a few times which is right in that exact spot (same area with a couple different spots within that small area). So, I'm wondering if the "white spots" are my bite marks. When I bit under my tongue it was super painful because that skin is so thin & whoever heard of anyone biting "UNDER" their tongue??
I figured out I must've been turning my tongue up & sideways to expose that area of my tongue to the area of the lost tooth thereby making it more vulnerable to biting. Make sense to anyone??
I've googled it & that's how I got to this page. I read some stuff about salivary duct blockage & also swollen white bumps on tongue (tip & sides, one or a few). Although, those two are different (I think) but I understand the white bumps on tip of tongue are swollen taste buds resulting from salty or spicy foods and will go away in a couple of days & NOT to take them off (which I never have!) I wonder if the two are related or are the same thing.
I haven't had a chance to look more into blocked salivary gland or duct or salivary stone. I also noticed when my "bubble" is swollen & I thrust my tongue or the "bubble" spot towards the front of my teeth to get a closer look, that looking behind or beyond it that section (like going towards back of tongue yet attached to "bubble") there looks like a slightly swollen linear section too! ! I'm not sure if that is just the muscle from me pushing my tongue forward or if it is more swollen tissue.
So, for now I'm leaning towards salivary duct blockage/stone. I will try lots of water to drink daily & gargle w/hydrogen peroxide, water mix - I eat some unflavored yogurt w/active enzymes? or active something. I will also probably drink some cranberry juice too. I will stay away from salty & spicy foods to see if it clears up! If not, I will have to go to doctor to make sure it's not cancerous.
I will definitely be chewing a lot more carefully too. I will chew slower, NOT talk & chew at same time (which I shouldn't be doing anyway) as well as make SURE my tongue is flat while chewing so I don't bite under my tongue anymore! !
WHAT DO YOU THINK??
