I had SMAS facelift 4 years ago and have had hypersensitivity on my upper right cheek and small area near my mouth when anything touches the area. More recently my lower eyelid on that side feels tingly and cold and afollows the nerve to my upper cheek. Anything that touches my upper cheek I feel along my lower eyelid and sometimes the corner of my upper. I feel as my skin is starting to sag that there is tension on the nerves damaged and I am getting more uncomfortable as time goes by.
