I'm worried about the red bumps on the back of my tongue with a white coating any idea what it could be i'm only 15 there is no pain at all

Taste Buds: When most people first notice them they are often freaked out by these bumps on the back of the tongue, which are usually just the taste buds! If not painful, the white coat is likely also a normal finding and should be able to be lightly brushed away. If painful or difficulty swallowing or progressive other things need to be looked into.
