No feeling in breast skin

Avery

I nursed my exclusively for 7 months and the first 4 months I pumped constantly on top of that. My supply dropped and he is fully on formula now at 9 months. I’ve noticed that I have almost no feeling in the skin on the bottom side of my boobs. I can’t feel anything if I just scratch it. To feel anything I have to pinch hard. It doesn’t tingle and doesn’t feel like numb there just isn’t feeling when I touch it. Has anyone else experienced this?
