That’s the only word I could use. I’ve been exhausted but it’s been in my muscles too. It’s been hard just getting around my condo because of the muscle fatigue. I almost went into my scooter last night. Every step is difficult to take not only in my legs but in my arms holding me up with the walker. I don’t remember feeling this way last time but last time they messed up and split my dose. This was my first full 600mg infusion. I keep expecting an adverse reaction to the steroids that was given, that never came it’s this fatigue that’s killing me.
