Hey @Trikki2. Hmmm...that's a tough one because as we know every one is different.
I had lumpectomy and node clearance as well. The acute pain started leveling off after about 6 wks.
However, the discomfort, tightness,up and down swelling and occasional pain has been and all over the place to varying degrees for 18 months. Not really a problem during the day with a bra on but is only now starting to feel somewhat more normal without. I had radiation as well so that attributes to some of the tightness and changes in the skin, so probably why its taken so long.
On a good note though finally it's getting there.
All the best for you chemo. Fingers crossed you sail on through.
