Yes yes yes!
Breath taking, isn't it
I perhaps don't get it to your degree. I had chemo, lumpectomy & radiotherapy back in 2015
One thing that I believe helps me, especially along the front, is a long story. I developed lymphoedema very early in my recovery. A couple of years later, my lymphoedema physio employed a massage therapist to undertake a lot of the lymphatic massage. But this time, I'd also developed bilateral wrist issues that was preventing me from doing my own self massage, so I started having regular breast and arm lymphatic massages. About 12-18 months ago, the practice bought a Lymphatouch device, to aid lymphatic massage
What your question tonight has made me realise, is that I am getting far fewer anterior spasms these days. Just under my breast I have some quite deep oedema, and my massage therapist has also spoken of doing some myofascial release work there, by using the device on quite a high setting.
Considering that I still get the spasms in my back, the myofascial release work is the only difference that I can think of
This could all have been a really long winded way of saying maybe try to find a massage therapist who doe myofascial release work
Hope this is helpful
