Hi @Jinni, sorry you find yourself here but welcome. My first bc surgery (2003)was a lumpectomy and full node clearance and it was the latter that was the most painful to get over. You’ll probably find that it’s healed and you feel more normal around 3 -4wks.If swelling persists,you could have a seroma which is a collection of fluid. Your surgeon can drain it if necessary. Don’t hesitate to see your surgeon or breast care nurse if you are worried- they should also advise on your skin issue. Something like Moo goo or Qv or vit e cream might be soothing in the interim. Keep up the gentle arm exercises. I was slack and didn’t and by 6wks post op,I couldn’t lift my arm any higher than my shoulder- it was bad! I needed intensive physio to fix it. Best wishes for your recovery and come back here for support.Gentle hugs xx
