@CeeCee I also had multiple areas of cording from the axilla clearance surgery down my arm. The physio worked on it and they went probably within a month or 6 weeks of ongoing physio and daily massage/ exercises. It can be quite debilitating, as you hit the limit where it is. For me it was my dominant arm and hand and I just kept using it every day to its capacity, keeping the compression garment on and stretching/massaging. You or partner/friend can give it a little massage you won’t damage anything and weirdly they pop as they resolve. I am 3 months on from surgery and they haven’t come back. Good luck with the physio.
