3rd shoulder surgery

My shoulder "is a total mess" according to my ortho. I've had 2 surgeries already, neither which have kept it from dislocating and only increasing the pain. After 5 dislocations last week I'm having and mri and artrogram to figure out a plan on if I should do a 3rd. Another complication is I have seizures.
I need some stability in my shoulder, will not do a fusion, neither will dr....but I am so afraid of more surgery.
the pain I have after surgeries is alway not able to be managed in the hospital or out, and it takes months for the severe pain to go away, and then the pain never ends.

if the test show surgery may help stabilize this thing, would you do it?
I live with chronic subluxsations, and basically chronic dislocations. It comes out in a way that is really hard to relocate.
my other arm is screwed bc of nerve damage and chemical burn, so I have NO good arm anymore...
