Welcome to the club :)
None of us want to be here but it is a wonderful site and you'll find lots of support and friendship here. Like you have just done, you can post your story, rant and rave, ask questions or just have a chat. There are no judgements just understanding. I was diagnosed five days before Christmas in 2012 and I've come through a lumpectomy, 6 months of chemo, bilateral mastectomy and immediate reconstruction and am continuing to have Herceptin and five years of hormone treatment. I had two ca lumps, one was TNBC and the other was ER & HER2 +
I only had mild cording after my lumpectomy and it cleared up with exercise. I think you are doing all the right things but you may want to investigate going to a Physiotherist that specialises in this area. Your Breast Care nurse or hospital could point you in the right direction. You probably know all this being a nurse :)
Live you, I did have an experience of stitches popping out of the suture lines in my breasts and belly button after my mastectomies. I was told that the stitches were the desolving kind but a few obviously didn't. It was about week four or five after my surgery and I was massaging with bio oil and I felt two in my left breast scar and one in my belly button. I was really concerned so I phoned my plastic surgeon and she said "oh it's okay, just pull them out". So I did. I had visions of the whole suture line unravelling, it was weird. But it was all okay.
Perhaps you can go to your GP and have it checked or call your surgeon.
Good luck with the rest of your chemo. I hope you're not suffering from too severe side effects.
