Should I be concerned and gp to ER?

Yesterday I was sitting with my smoker colleague and was inhaling all the smoke.I ate a fast food where I have never eaten before with big puffed potato french fries(so yummy but wondering what makes them that puffy) and I get a headache which turns out to be a sharp pain in my chest and all my joints hurt.Today I feel so tired with headache and dry mouth and has to come home early.Is it the smoke or the fast food that makes me sick?
