I'm 3 weeks out and I'm having abdominal pain like at my belly button incision site all around there and I have constant cramps in my side/back area. Anyone else?

I get cramps in my side that go around to my back. I actually stayed an extra night in the hospital for it. The dr gave me lorazapam. I do wish they they had sent me home with a muscle relaxer. I think my recovery would be much easier. I pulled that muscle running from my main incision. It is slooooow healing! Btw I'm almost 3 weeks out.
