Weird pain help!

Angela

I have my doctors appt tomorrow but for the past two days I’ve been getting a “muscle spasms” that last for a few seconds right above my stomach like the opening of my stomach is the best way to explain it. The pain radiates to the same location on my back so right in the middle of my back. It appeared out of no where yesterday and it makes me feel sick it lasts all day but periodically please help!
