6 weeks post-op my abdomen is still feeling tight and numb. What can I do to decrease the tension and numbness? (photo)

There can be some numbness that is usually temporary due the procedure. The tight feeling is a natural part of the healing process. Depending upon the extensiveness of lipo, it could take months for all the tightness and numbness to resolve.  I do not recommend lymphatic massages, but if you PS does, follow his/her protocol.

Thank you for your question and photo. At six weeks you are still early in the healing process. Your skin has the appearance of "orange peel" which is consistent with swelling even in the dermis or skin. This will improve over time, massage will be beneficial and stretching exercises. Be patient, might take a minimum of 6 months to return to normal including regaining skin sensation. Good luck with your healing.

Thanks for writing,You are experiencing exactly what you need. Tightness is suggest you are healing, making scar and improving. You have to be patient, this will take months, but it will improve and in the long run the results will be great. Good luckStephen M.

Hello dear!!
Thanks for the question and provided information as well.
You are still early on the healing process, it can take up to six months to see your final results, so please be patient. At the stage you are in, inflammation and discomfort are normal.
I suggest my patients to try the lymphatic massages and to use a full body compression garment, 24/7 for the first 3 months, and after that, for 12 hours a day for 3 more months, to get the best results.
It is important for the compression garment to be very tight, for it to help with the swelling, after surgery. Please, follow up close with your plastic surgeon.
Good luck :)

what you describe is normal postoperative sensations after liposuction. These are typically questions patients discuss with their surgeons during their postop visits.  That would be a pretty good place to get an assessment and reassurance. It takes 3 to 6 months for things to settle down and stop changing.  Best, Mats Hagstrom MD
