Lumps and dimples on my stomach 2 weeks after liposuction. is this normal? (Photo)

Ninety cubic centimeters is less of an amount than any suction I have ever done. I get more than that amount from an average chin. Your level of fitness not withstanding, I don't get it. Is your surgeon a board cetritified plastic surgeon who has done a ton of liposuction, or is it a surgeon from another specialty who took a course on how to do lipo dissolve, smart lipo, or laser lipo!  To cause waves with that small an amount of fat taken is unusual,  but please listen to his (or her) advise, and wait at least six months before having anything done. If your surgeon isn't board certified in plastic surgery, please seek another opinion from someone who is and who does this surgery routinely, before you let anyone else revise your surgery. Remember that it's too early to address the problem you may, or may not, have...be patient and good luck. 

Contour irregularities such as those in the photograph are fairly common after liposuction. These will gradually subside as swelling subsides.

It appears you have asymmetries but since it is so early, it may just be swelling.  At this point I would suggest ultrasound or massage treatments and exercise/diet.  If after a few months they arent improving, then fat transfer, additional liposuction or noninvasive treatments like Liposonix or Ultrashape can be very useful here to address only the specific areas without having to undergo another surgery.  I suggest seeking someone who has experience in revision procedures and knows how to use and does on a regular basis use these newer non-invasive devices.  I would gladly see you or I would suggest my good friend Dr. David Amron in Beverly Hills.  Anyone who does these procedures regularly, regardless of speciality, will be better than someone who has little training.  I am a Dermatologist/Dermatologic Surgeon with years of experience and 100s of cases with no complications.  Plastic surgeon or not, you want an expert with attention to detail. I wish you the best, Dr. Emer.
