Thank you for sharing your question and I am sorry to hear of your recovery difficulties. The bumps may be where your sutures were tied to lend support to the soft tissues of your neck and may improve as your results mature. I would verify this with your surgeon with an in-person examination and discussion of your results. Best wishes.
I recommend following up with your Doctor for a formal evaluation. It can take up to 6 months to have your final results with a neck lift. To improve final results, I recommend a combination approach with thermage/venus legacy and Kybella/Ultherapy. I recommend getting a formal consultation with an expert. Best, Dr. Emer
