I just finished my 7th shot. Alot of my pain and stiffness is gone, but I am so exhausted, all I want to do is lay down and nap. It seems as if I am in a fog, and have a hard time concentrating on things. I am a bit disappointed too. I guess I thought is would make me feel normal again. I felt really good the second and third week, then this fatigue started to set in on me.
