I was on prednisone for a allergic reaction to the flu shot I got last week. At first I was on 80mg a day for four days by the fourth day had really bad headache, dizzness, nausua, leg cramps and weakness could hardly walk felt really weak. They cut me back slowly to 60mg,20mg then,10mg to wing me off. I still feel bad,will these symptoms leave now that I am off of it. Did anyone else ever have these symptoms?
