Pain three years after neck and lower facelift

Neck and lower facelift 3 years ago. Pain from the onset and still not resolved. Lots of burning and pulling sensations. External numbness to both sides of the face and neck. The pain seems to run along the trigeminal nerve path. My head feels so tight and I have constant headaches. My neck feels tight. I could go on and on. I've had all types of therapies and seen specialists and doctors. I am on pain killers and have tried anti seizure drugs. Nothing works. Original surgery done o/s.
