Hi @spark mine is more of an ache than a twinge – the pain is there all the time and not just when I move my arms, although it is a lot worse when I lift my arms or press the area. I’m going to rest for a few days and if the pain doesn’t go/gets worse I might ring the nurse. I did browse the internet earlier and pain in the armpits seems quite common, especially early on. I was just a bit concerned that mine started 11DPO. Hope your recovery goes well xx
