Tightness in thighs limiting motion and questions about scar opening.

I am 3 weeks out from a thigh lift with lypo to my knees and sides/backs of the thigh. My thighs seem very tight. I have some pain in the scar that goes down to the knee and I am still very limited in motion. Is this normal? Earlier on I popped 2 stitches trying to sit. I was given SSD ointment to heal it from the inside out. He put a stitch above and below the opening. I avoid sitting as much as possible, only stand or lay down. Will this heal as a straight line? Or will it be a wide scar?
