Tiny lumps in mouth?

amylala98

For as long as I can remember the inside of my bottom lip has been filled with tiny lumps, that kind of resemble cellulite. They're all very mobile and painless and i just put it down to biting my inner lip as a habit. I woke up this morning with one of these lumps quite sore if pressure is applied to it, extremely hard and inflamed to a pea size, my doctors are fully booked up and I am worrying as to what this lump could be. Its very noticable, as opposed to my other lumps which are only noticeable if i stretch my lip outward;
