<s>[INST] I have small black lumps on muscle tissue under tongue. It is attached to the muscle that runs down the middle of underside of tongue. Two of them. One more is forming, it is still pink. They are painless. slight sore throat a few days ago, now no discomfort at all. [/INST] Hi,welcome to HCM. i understand your query. IT may be mucous retention cyst, ranula or lymphoid follicle. It requires local examination for confirmation of diagnosis followed by treatment. So better consult a near by doctor for the same.Good luck. Thanks. </s>
