Axillary lymph node clearance

Good afternoon all. I had a lumpectomy and sln removal on 2nd December.  I got my results on 29th December and unfortunately the cancer was found in the lymph node they took away. I now have to have another surgery to remove more lymph nodes and chemotherapy.  I'm absolutely devastated  asi also found out my cancer, although only 13mm, was grade 3. I'm currently staged at 2a but I've just got a horrible feeling it will have spread to further lymph nodes. Has anyone had a clearance and if so how was the pain afterwards and recovery time? Love Donna
