I had laparoscopic cholecystectomy on June 12. Two days ago I carried my son up to bed (4 weeks post op), felt a little pulling

looks like only part of my question was posted.

to continue with what I was asking.

   felt a little pulling in the upper incision when I was carrying him. Now two days later I still have a dull ache there and it is a little tender to touch.  could I have done damage by lifting too soon?  I thought since I felt fine, and it had been 4 wks that I was okay to carry him again.  (He is probably 30-35 lbs)

Thanks.
