Back pain after implant removal and second implants

Lee. I have similar to you except the muscle was used as a repair because I had wound healing issues so same surgery (already had implant for 4 years) just doesn’t look any good.
i do occasionally get what I would describe as a cramp or spasm in the muscle around armpit height but in the back (if that makes sense). Mine does pass after a while. It sometimes happens if I twist funny in bed. All I do is try to relax it a bit & gently move/stretch my arm. The Lat Doris surgery was in 2015.
