Two days ago I fell down 8-10 stairs. I was on pain the night of and I did hit my head but had no nausea or anything that night. Now I m in very bad back pain , having difficulty taking deep breaths, have nausea, headache , and bring cloudiness-misspelling and difficulty focusing vision . I m doing to the dr but am at work right now. Should I leave work or should I be ok for a few more hours?
