Lumps mid/lower throat 7 months after neck lift (Photo)

Dear Doctors, Thank you for taking the time to advise. I am a 60 year old female in excellent health. I had a necklift procedure in combination with facelift. 7 months ago. Everything has settled very nicely apart from these softish lumps . These were not pre existing but developed after procedure. I was thinking that it was post operative swelling and would dissipate over time. I feel that the size of the lumps has decreased probably by about 20% only over this time
