Weird bumps on tongue

[123tre]

Hi guys,

So last Summer, I had a load of weird bumps on my tongue that would appear in the morning and disappear by the evening every now and again which were really painful! I would say every 4 months since then I get one then it goes away again. I went to the Doctors last Summer and they didn’t seem too interested and put it down to stress after I suggested it could be stress related. Any clue what they are?? Any suggestions would be great 😄 (ive posted some more pics as well cause the bumps seem to vary)

You might be chewing your tongue in your sleep
