lymph nodes are busy doing their job. Sometimes they get overloaded. You have just had chemo and lots of fluids so your body will be trying hard to process all that . Don't panic about it. Just wait and see how you next scans go, ask your medical person to check . If they don't settle down you could see a lymphoedema therapist as they the ones who can teach you how to move fluid, but that can only happen after you been clearnace by doctor.
I had breast cancer 18 years ago and had 11 nodes removed in my armpit, i know how uncomfortable a puffy armpit is.But I knew that was lymph fluid. Excess fluid does cause pain for me. But have had to learn how to keep swelling down with self massage, deep breathing, compression, skin care, lymph moving movements. Our lymphatic system is amzing, but some gentle tai chi is great for armpits , breathing and arm waving, slow body turning . That should be safe for you to do until you get doctor clearance. Try it a little ,gentle sequence for a short time, then wait, and see if it helps. Next time you see your doc ask about lymphodema risk in relation to your specific surgery and if you need a referal .Or just to wait until post surgery and chemo settles down. There are a bunch of nodes alos in the middle of our chest, and our thorasic duct nearby that handles all the lymph fluid, if they poked around near there. Plus our heart and circuilation system effects fluids, and digestion ... so many things can effect our 'fluid ' balance. Hope your feeling better sooon.
