D4 post lumpectomy itching

Hi everyone,

I was diagnosed with ILC R) breast hormone +ve, HER2-ve at the start of April. I'm D4 post op lumpectomy and sentinel node bx. I have a follow up appointment next Monday.

Pain has been manageable, but today I've noticed my breast is so itchy and I had some shooting pain. I can't see a rash but honestly it's hard to tell with the bruising. 

Did anyone else get this? Did anything help? Im curious if it's the nerves trying to heal.

I'll need radiotherapy, so also keen for any tips to prepare for that.

Thanks xox
