There are many reasons for the lumpy pain at the base of the tongue, such as burning mouth syndrome, lobar papillitis, tumors and so on. 1. Burning Mouth Syndrome: Burning Mouth Syndrome can cause the phenomenon of lumps and pains at the base of the tongue, accompanied by an obvious burning sensation on the tongue. 2. Lobular papillitis: chronic pharyngitis, frequent tongue extension, cuts and dabs, etc., can cause lymphatic circuits to be impeded, leading to inflammatory reaction of the lobular papillae at the root of the tongue, resulting in pain and bumps at the root of the tongue. 3. Tumor: malignant tumors of the tongue can also cause tongue pain and abnormal tongue sensation. In addition, oral cancer can also cause tongue pain. As there are many reasons for tongue pain, it is recommended that patients go to the hospital in time and take standardized treatment according to the doctor’s instruction, and do not treat the problem privately, so as not to lead to adverse consequences.
