Burning in my shoulder

I have a question for everyone. This is my first long term pregnancy. I'm currently 22 weeks. and for the past couple weeks anytime I sit down I get a burning feeling in my right shoulder just above my shoulder blade. It doesn't have a sharp feeling or anything just burning and a dull ache. It sort of feels like if someone put a space heater really close to your skin for to long and didnt move it. I wasn't sure if anybody else experienced this.

I know shoulder pain can be related to gallbladder issues and preeclampsia but wasn’t sure if burning was the same thing or if it’s normal.
