Hello, I had / have this too & noticed that the oncologist has written i had Thrombophlebitis in my notes (though not explained this to me in the appointment when I mentioned the pain.)
Oncologist 2 was very cross I hadn’t used a pic line with EC. I’ve definitely noticed that mine has eased & whilst I know this is often the advice for everything - drinking gallons of fluids definitely helped it ease. I do have a bit of pain / discomfort in my upper arm now though. I massage it a bit but am hoping that once chemotherapy is long in the past it will ease up.
