I certainly hope it's normal. My surgery was 1/19. I can walk for several miles at a pop and swim for as long as I like with no pain, but certain pt exercises are still difficult for me. My adductor and abductor muscles still need work. I've been working at stretching my adductor by hanging my leg off the bed and, yes, it hurts to do this. Side clamshells are more difficult for me than side leg lifts (go figure). My glutes sometimes hurt. The muscles are sore and hurt because they're still weak. The point of the pt exercises is to make them strong. Then they won't hurt anymore. I still can't roll onto my right (surgical) side because it remains tender. I was amazed at how weak my muscles were after surgery, and they sure are taking their sweet time at strengthening. But they are getting better and stronger over time. As long as you are continuing to improve I wouldn't be concerned.
