Hi
Every individual has a different pain tolerance and therefore a different experience with surgery. In regards to pain, there are two periods to consider. One is during the operation and the second is during the postoperative recovery. The pain during the operation for liposuction of the chin and neck area should be very mild depending on the type of anesthesia. In the simplest situation the procedure can be performed under local anesthesia and the discomfort would be primarily from the injections to numb the area. At the other extreme, the operation can be performed under general anesthesia and you should feel little during the surgery. Between these are options where local anesthesia is used along with medications to provide various degrees of sedation during the procedure.
During the postoperative period the average person tolerates the discomfort very well and any pain can be well controlled with oral medication. I would recommend a consultation with a board certified plastic surgeon to determine what type of anesthesia might be best for you. He or she can also give you idea as to the type and degree of change you may anticipate.
I hope this information provides some help to you and that you are able to overcome your fears to undergo the procedure. Best wishes and good luck to you
