At one month out, you could still be seeing normal swelling. What type of procedure did you have? Keyhole, or lipo alone? Revisions are pretty common, and you may choose to get one, but you'll probably want to wait at least 6 months to let things settle a bit first. (My surgeon recommended waiting 1 year before revision, but he wound up doing it at 10 months.) Have you spoken with your surgeon? Nothing wrong with wanting the best results you can get!
