@LMK74 That really sucks!! Sorry to hear you have gone through chemo to have it not be successful. How disappointing, frustrating and scary for you. Just another shock to your system. I had three lymph nodes removed which is nothing compared to a full node clearance. However I do seem to have oedema of the breast not my arm. It is annoying, but it doesn't necessarily mean you will get lymphoedema in your arm (fingers crossed I'm hoping). As for your last chemo, can you see your medical oncologist? I'm sure they're in contact with the surgeon and can give you further advice on why you would need your last chemo session.
Here's hoping you get some answers and will feel at peace with the decisions to be made.
