@macadoo My first suggestion would be to speak to your doctor (rheumy and/or PCP) and see if you are anemic or to help look for a cause outside of PMR for your fatigue. Fatigue can be a symptom of many problems, even depression. Eliminating any other cause would leave you with where you are right now, thinking it is PMR and steroid related. It could be that PMR is the cause but it could be something else and the steroids were covering it up. Have it checked out so you and your doctors know about it.
