I’ve got bulimia and I’m on lamictal for bipolar disorder, I now have mushroom looking lumps on my tongue?

I’m a 20 year old female. I’ve got bulimia and I’m on lamictal for bipolar disorder. Three days ago I felt like i had a hair stuck at the back of my throat and it was like I couldn’t get rid of it, then I noticed right at the back of my tongue I have about 6/7 (I can’t see exactly how many as I have to poke my tongue right out) little mushroom looking lumps. They’re not sore or painful just irritating. My bulimia is really bad at the moment and i’ve been sick a lot so I’m wondering if it’s connected?
