Painless bumps. Being foolish pls help!

Hi. So I have these bumps On the tongue which is close to the throat. I went to an ent in hyderabad at nmdc. Dr prasad raju. He just saw it and said those are taste buds swelled up just because of infection and nothing is there to worry. Im still worried. He just said I needdd assurity that nothings wrong. Those are bumps which are so many on the inner part of tongue near to throat and I dont smoke or drink. So is it normal for the taste buds to swell up. It looks like bumps. Theres no bleeding or pain. Ive been given 5days dosage of Aceclofenac nd paracetamol, Levocetirizine hydrochloride, phenylephrine hydrochloride and Cefpodoxime. We don't filter water before drinking. Is it because of that. Idk what the reason is just tensed that is it oral cncer or something. I searched on google and it said this so I am damn scared. Ik im being foolish pls help
