Is this the start of LE?

It could just be scar tissue. I was told to message my scar by gently walking my fingers back and forth over it a few times a day. I also have cording which felt like pulling when I raised my arm mostly in my arm pit and a sharp sudden pain if I went to far. LE feels heavy. My breast felt like it weighed more it was pinker and warmer than my other breast. LE started with what I would describe as a mild achy feeling, sore but not sharp stabbing or sudden pain, the soreness increases with activity.

I don't know if that is how everyone with LE would describe it because LE seems is an individual experience, effecting people differently.

Hope this helps

I went to an LE specialist (renowned). He said by visual assessment, palpation and objective quantitative measurements my symptoms (similar to yours) didn’t look like LE; but from my qualitative description of my symptoms and when they appeared (especially finger swelling when wearing a gauntlet on a long flight) he was classifying it as borderline stage 0 LE anyway (primarily so Medicare would cover my upcoming PT/OT sessions and perhaps my supplement might pick up part of the cost of a glove). He also doesn’t prescribe compression garments to node-negative patients with 4 or fewer nodes removed by SNLB, which SNLB area wasn’t irradiated, nor does he recommend compression garments--not even for long flights or moderate upper-body exercise--for LE prevention in patients not definitively diagnosed with it. (He prescribed a glove for in-flight comfort but only as needed). And my enlarged and hardened tumor cavity is not LE, but rather just a seroma aggravated by rads.
