6 weeks post-op. Lump in buttocks after BBL. Is this something I should be concerned about? Will it go away? (photos)

Without examining you in person it’s difficult to know exactly what is going on. I’d suggest booking an appointment with your surgeon to be examined, they’ll be the best suited to figure out what exactly that lump is. 

Though an exam would be necessary, this may represent fat necrosis. This can soften over the course of 6 months to a year. These areas if larger or painful can be surgically excised. Contour irregularities can then be fat grafted.Kenneth Hughes, MD, ABPS Board Certified Plastic SurgeonLos Angeles, CA

Hi and welcome to our forum!
Congratulations on your recent
surgery!
The operative result is not yet
apparent as there are multiple factors at work. Inflammatory swelling will
totally obscure the size and configuration of the buttocks. Also, the skin
and soft tissues must adjust and reshape to accommodate the added volume
beneath. Lumps and bumps may represent only localized areas of increased swelling, but also could represent hematoma, or seroma. If small, spontaneous resolution will occur. If large, fluid filled cavities may require aspiration. Your surgeon will be able to differentiate by examination.
Follow the advice of your surgeon
and continue follow up care.Best wishes...

Good day and thanks for your question.
The lump you are showing can be secondary to several things, could be a seroma, trapped blood, a fat graft accumulation, etc. Best you can do is to have a consultation with your surgeon to decide what is the best aproach to solve it like aspiration, antibiotics, massage, etc. With a good aproach usually lumps disapear in some months.

It’s not unusual to have an area or two of fullness or tenderness 6 weeks after a BBL. It is always smart to see your PS in follow up to confirm the exact nature of this lump. Massage, aspiration or a course of antibiotics may prove helpful. I have not seen such a lump persist or be a long term problem. Best of luck.
