Hi. It would be hard for anybody in this forum to tell you with any certainty what those lumps are, since we haven't actually examined them. There are lymphoid tissue (something akin to lymph nodes) normally located in the back of the tongue. Your description of those lumps seem to match a description of those lymphoid tissue. However, if those lumps really bother you, the best thing to do is to go to a doctor (an otorhinolaryngologist or ENT specialist would be appropriate) so you can have those lumps checked. Most probably it isn't anything serious, since those lumps don't seem to be causing symptoms at all.
