Sitting is very uncomfortable after Tummy tuck. Any suggestions?

I Find sitting gives me hard sensation in tummy and a sort of fuzzy feeling. It makes sitting quite unpleasant . Lie in down is better but not perfect . I am six weeks post tummy tuck plus lipo to flanks. I feel a pulling on my left hand side as if a muscle is moving about - might this just be scarring? When does the hardness go and why does sitting trigger it off most? Thank you.
