Rash whilst breastfeeding helppp

Anyone had a rash like this whilst breastfeeding? Been doing it for 6 months. The worse rash came up 2 weeks ago and the other one started this morning. Making feeding and pumping really painful. My doctors won’t see me until may 30th so thought I’d see if anyone had any ideas on what to use to help or what it was.

It’s on the nipple too for reference
