I have been dizzy and lightheaded for 5 weeks now. I was told I had a sinus infection and given round of anibiotics. Then still having the same feelings family doctor put me on steriods ( prednisone ) for 5 days. Felt great while on it. Then on the 6th day (after prednisone) same feeling of dizzy, room spinning feeling. Dr. perscribed another 5 days of prednisone and again felt great. Now I m on day 3 after the prednisone and still having the dizzy, lightheaded, room spinning cloudy type feeling, and now having weekness in left hand . Also feel pressure above by eyes, nose bridge area. Is it just a sinus infection? What is wrong with me?
