You should definitely see your surgeon sooner rather than later. Those areas do look a bit concerning but an in person evaluation is recommended highly.
Thank you for your question and for sharing your photographs. Though nothing replaces an in-person examination I am concerned that your black spots are areas of necrosis or burns to the skin surface from the liposuction. I would see your surgeon immediately to discuss your current results and have appropriate wound care instructions given. Best wishes.
Thanks for your inquiry and sorry for your struggles. I think the most important thing is to closely be monitored by your plastic surgeon. Ask your surgeon to clarify the amount of NitroBid you can use, what dressings to use, and about shower and activity restrictions. I wish you a speedy recovery.
