Can nerve damage from a facelift cause hot flashes 5 years post op?

Hi I am 62 years of age and I had a face lift about 5 years ago . When bandages were off and bruising had gone . I noticed I was now having hot flushes across my face which I didn’t have before surgery. I told the surgeon about this and he said it was my hormones due to menopause and told me to take soya . I went on HRT which did help . Now I’m not on HRT as been on it for over 5 years and came off due to cancer risk . My face is now more hot flushes causing me to feel really hot and sweaty . I’m not sleeping because of it . I really think that this is not Menopause but Nerve damage from face lift . What are your thoughts and if this is the case is their a treatment I could have for this ,
