Do my inner thighs need to be re-stitched? Is this normal or should I be worried?

I had an inner thigh lift 16 days ago and my scars started opening and are very painful. My PS said this is commin and has advised me to cover with gauze. However I do not see any improvement and my inner thighs are still bulgIng like they were before surgery. Also the scar on my right side extends out while the left in is my groin. Is there anything else beside covering with gauze that I can do to help with healing. Should these scars be re-stiched? My PS said he has never had to re-stich inner thighs.
