I don't know if this is an std or not, PLEASE HELP?

I don't know what to do. I'm a teen girl. I gave a guy head 10 days ago. He said he's only had sex with one girl, they were both virgins apparently. Today my mouth, especially tongue, felt tingly/burning and it scared me. I found big bumps in a v-shape on the back of my tongue, and that really scared me, but apparently these are normal? Still not positive about that. Now my throat is hurting, and the inside of my mouth still tingles and just feels weird. I asked my mom if the bumps were normal and she said yes. I really don't want to tell her what I did. I know it was wrong. What do I need to do?
