Burning feeling top of bump?

CW

Is anyone else have the sensation that the top of their bump is sun burned? That’s the closest feeling I can equate it to. It is in the center of my bump, at the very top, close to my bra line. Sort of like heartburn - but on the outside? My bump isn’t sunburned. It’s has never even seen the light of day.

Google tells me it is likely nerve related, but none of my pregnant friends know what I’m talking about.
