8 month post op and my breast tissue appears to be separating from my implant. Is this something that could have been avoided?

I’m 8 month post op and my breast tissue appears to be separating from my implant. Sometimes in the indented area it tingles and burns. And if I lift anything heavy with my arms it competlely separates. Is this something that could have been avoided on my surgeons end or mine? Because I’m very unhappy with the appearance.
