Is it okay, that I ask why you had plastic surgery, what happened? Were you injured in some sort of accident?
Was the surgery for reconstructive purposes?
If this was cosmetic surgery, were you going to have some sort of feature change? I'm only asking so that if there is some way I can find info for you, have you spoke with a lawyer in regards to malpractice case?
I am sorry to hear and see you are suffering, though you say you do not want any medications, there may be some that can be of some help, try to be open to any possiblities that may be of some help to ease the pain somewhat.
I wish you well, and hope you'll decide to hang on.

Please take care now,
DE
