My compression garment is damaging me. What would you advise?

I had a full abdominoplasty and vaser liposuction to the flanks a week ago. I have been wearing the compression garment I was given by the hospital which is digging at my waist causing deep bruises which hurt more than any of surgery I have had. It is also strangling my thighs as it is so tight. I can't take any more and have swapped to a pair or Spanx I happened to have with my Macom binder worn on top. Will this be sufficient or is there any other garment you can recommend? Many thanks.
