Is it normal to have neck pain 8 months after facelift?

It is unusual to have pain lasting so long after a lift.  It is possible that sutures placed deep in your neck region to tighten the neck line have entrapped a nerve that is causing your pain.  An exploration and release of any scar or sutures in the area may help. 

It is unusual to have pain 8 months after surgery, and suggests that you have extra scar tissue in the area of the neck that was surgically undermined at the time of the original surgery. Sometimes massage and physical therapy to stretch the area can help. If the pain is localized, then sometimes a steroid injection may help. I would consult with your surgeon. A definitive diagnosis would require an in-person examination.

I would advise you to contact your plastic surgeon. It is always best to follow up with any symptoms post surgery even if they may not be related. Make sure you are speaking with a Board Certified Plastic Surgeon. All the best during your healing and recovery process!
