Extreme strangulation feeling & numbness 6 years post-op lower facelift & neck lift, what could help?

I am a 53 year old woman, 6 years post op from a lower facelift and necklift. For 6 years I have an extreme strangulation feeling and numbness on the sides of my face, chin and neck. I have seen dozens of doctors including plastic surgeons, ENT, pain management, PT and neurologist. No one has been able to help. I've tried exploratory surgery, PT, topical ointments, nerve block injections, botox injections, neurontin, muscle relaxers, acupuncture and needling.
