Abdominal Spasms After Tummy Tuck Normal?

I had TT a week ago and have been woken up the last few night by muscle spasms of the abdomen. I remember this also happening after the birth of my children. It seems to be the body's way of healing, or perhaps due to the increased stimulation and irritation. My concern is the integrity of the muscle repair. I am taking muscle relaxers to help. Should I allow the muscles to cramp? Will it "hurt" anything? I do plan on seeing my PS soon and discussing it. Thanks for your time.
