Well to elaborate, it really depends on the surgery. For example if someone got a neural implant to help with reflexes, thought process, etc. they'd most likely develop a severe form of PTSD from the surgery itself and the technology, perhaps memory relapses or severe migraines. I'm seeing a place where technology is advanced, but not perfect. People go mental because of it, synthetic arms don't feel...right, robotic heart transplants feel cold, etc.
