Opinions or answers?

Really just curious I guess as to what is going on with my body.. I've been having some stand things happen.. Like things I eat that I've never had any problems with burn the inside of my mouth now when eating them, I feel like I have a pill stuck in my throat/stomach area and it makes me nauseous and now my boobs have been pretty sore but it's like around my boobs, like the edges I guess you could say.. And I just really don't know what it is, and I'm not supposed to start for another two weeks. Any ideas on what is going on or has anyone had anything similar anytime?
