How do I get rid of chicken pox in my throat?

Nothing is working so far...throat drops, spray, gargling salt water, it feel like strep but my mom thinks it's chicken pox in there. It hurt to talk or drink or eat anything. I cant stand it anymore...what can I do!? If you say I need to go to the doctor, give me a good reason otherwise my mom won't listen and won't take me. =/
