My Mother was taking 35 mgs of Prednisone for Arterial arteritis. She has been reducing slowly (With Doctors orders) she is down to 6 mgs. The whole time she was on she would get terrible head aches and now they seem to be lessoning. I hope they go away all together. Overall she feels bad no energy, depressed. Is this common when comming off this medication? I can't find a good site that discusses the side effects when reducing Prednisone.
