Hi! I have not. I have had some good results needling old surgical scars in the periphery, especially when adding e-stim. I do have a colleague who reports some improvements in post mastectomy axillary scarring/cording with careful dry needling under the supervision of an oncologist and lymphedema therapist. I am also attaching a published case study treating chest wall tightness with dry needling and e stim. Although this does not answer your question, it is all I have to offer. Be careful in the presence of any limb or chest wall lymphedema. Sonya Worth

HI!
Looks like the case study pdf is too large to attach here.
Here is the reference:
Bell, L., Stout, N. L., & Geiser, M. B. (2019). Dry Needling for Chronic Breast/Chest Wall Pain After Breast Cancer Treatment. Rehabilitation Oncology, 37(3), E14-E16.
I can share the full text file if you have difficulty accessing it.
