Side effects of ending bf?

I’ve stopped breastfeeding almost 2 months ago. Since then, I’ve had severe itching in my armpits. Just my armpits. There is no rash, and I haven’t changed my hygiene routine. I use hypoallergenic soap. My breasts are fine, no engorging, infection etc. They have actually returned to pre-pregnancy size.

My question is have you had itchy armpits or any bizarre side effects associated with ending breastfeeding?

How long did your symptoms last and what did you do to combat them?
