I started Prednisone today at 40mg a day for 7 days to help open up my sinuses as I am getting over a sinus infection. I can't sit still and I am so anxious and nervous. This is odd for me because I am usually very laid back. My heart is racing and my heart feels as if it is skipping a beat. I don't think I am going to be able to finish these pills. It did the job. Yesterday I felt horrible and couldn't breath through my nose and now I can, but I can't stand this anxiousness. All these symptoms started about 6 hours after my dose.
