Yes, the muscle pull feeling just the other day. Actually was worse when I took in breath. Suspected all sorts of stuff.
But it was in my back and radiated all along the bra line to the sternum. ugh.
I did go to the chiropractor and got relief.
Is yours in your back or front...where exactly?
It could be gas as well...I get that, but different feeling, maybe because when I'm laying down and press...I can hear it blurping and I can actually move it along.
