Lymph node Scar red and sore

Had surgery end of May for lumpectomy and 4 lymph nodes removed from under arm and had 5 days of radiotherapy end July.   Scar healed fine where lymph nodes were removed but last few days the scar under my arm has become red and very sore at one end of the scar.  Is this normal?

  • I had the dye put in and it showed up that not just sentinel node was affected . I had the lymph clearance ,have done all the exercises and massage of the arm . I take care of that arm,try not to do heavy lifting ,massage it still ,wear gloves when gardening not to get cuts or infection .So far ,so good .It’s been a year with me..
