I have 10mg prednisone on hand. Sciatica is painful in left hip and back. How many can I take for four days. Dr told me six months ago. I forgot and she has not answered my call today. Have not taken any for 18 months. Also taking Tylenol for pain. Maybe should call local pharmacy. Please comment. I also have sore throat. Feel like taking a cold. I cannot think of anything else to tell you. Keeps saying not enough.
