Why do I have a bump 4 mos. post op tummy tuck? (photos)

Hello. Great question. Thank you for your pictures. You are still early in your recovery, swelling may still be present. I will suggest having an in person follow up with your surgeon to determine exactly the condition of your bulge. Best of luck with your recovery. Congratulations on your tummy tuck.

You are still in the recovery period from surgery and swelling is common at this phase.  I recommend discussing your concerns with your surgeon who can examine you to rule out complications.  As you notice an improvement with your binder, it is likely normal swelling from increased activity.

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 is normal. 
If you are not happy with the results then, l recommend you to make an in-person consultation with a board certified plastic surgeon for a proper answer and to talk about your goals and anything you need to know.
Good luck :)

Thank you for the photos you shared. At 4 months post op you likely still have some slight swelling that is occurring in some areas of your abdomen. This swelling typically resolves at about 6 months post op but with the symptoms you describe with your abdominal binder causing it to regress you may want to talk to your plastic surgeon about it. This way they can get a better idea of what is going on with the area and maybe even do an ultrasound to determine if there is a seroma (fluid collection) in the area. 

Thank you for your question and thank you for your picture.  While it is difficult to tell without an actual examination The bump could meet many things.  A bump on a scar could point to a hypertrophic area of scarring which normally is treated by steroid injections or massage with a silicone scar gel.  I tell my patients that areas of swelling take about 6 months to fully resolve.  
In any case I would keep in close contact with your plastic surgeon who will be able to guide you in the appropriate treatment.
