For the past week, from time to time, I have felt dizzy when lying in bed and turning my head, or sometimes when I m standing and have my head bent down, and sometimes when I sit up in bed. Also, not associated with the dizziness, occasionally I feel slightly nauseated, but not to where I m going to throw up. Should I be concerned? Also, I am supposed to start 30 days of oral steroids but don t know whether I should wait till the slight dizziness is gone.
