I think it’s just nerves starting to wake up / slowly reconnect.
I had a broken jaw and trapped the nerve in it. This was 15 years ago I still have numb areas around my mouth and says when it feels on fire from pins and needles. Nerves are just weird 😉
I also had my boob job Friday and was out today when my right boob woke up, bloody agony 🙂 just have to accept we are all different but get these weird aches n pains and annoyances over the first few weeks and months.
