I have been experiencing some pain in the lymph nodes under my arm on the non-cancer side since before I was diagnosed with TNBC 2 years ago. Nothing ever shows up on tests but it is almost a constant aching. I can feel the lymph nodes but the doctor says that is normal.
I did have the sentinel node removed from the cancer side when I had my bi-lateral mastectomy. Thank goodness it was negative.
I would love to know what causes the achiness and find a solution for it.
