Extreme Weakness, extreme excessive sweating, nausea, dizziness, itching, terrible headaches.In addition, I seemed to have contacted a moderate case of the flu. At least I had what seemed like the flu. However it is possible that it was just more of the same from the prednisone. My doctor gave me prednisone for a pinched nerve in my neck and a herniated disk in the same #7vertebrea. He gave me 12 days. As soon as I started taking it, I began to feel very weak, I had headaches, terrible exploding headaches. I found that I began to itch on my arm for no apparent reason, except for a bracelet in the area.In addition, I began to have excessive sweating, extreme sweating, the water would be pouring down my face. At that time, I would feel my heart pounding have some dizziness, and just overall bad feeling. It was debilitating, I spent a lot of time on the couch because I could not function in my daily activities. I went from exercising for 90 minutes to barely being able to get through 15 minutes. My question is will I go back to "normal" when this medicine gets out of my system. What is the half life of this drug? Should I do a detox of some sort. Worst of all, the problem with my neck has not really resolved and I will probably need some other sort of intervention. I never got that burst of energy that other people experienced with this medication.
