Hello welcome to HCM. I have noted your history. Your tiredness may be related to the steroid use. steroids cause osteoporosis or weakening of the bones by removing calcium from the bones. Long term use of steroids cause vit D deficiency and calcium deficiency. Vit D deficiency can cause fatigue and tiredness. I suggest you check your vit D and calcium levels. If they are low, you can be started on supplements. Usually people on long term steroids are on calcium, vit d supplements and bone protectors like bsphosphonates. I suggest along with the steroids you take these medications too. Wishing you good health Regards
