Yes, I experience this as well. It used to cause me to panic so badly because I feel like I can't breath that my whole body would go hay wire and I would collapse in the floor. GI Specialist has also discovered I have gastroparesis and that my stomach muscle are weaker than normal which traps excessive amounts of gas that has no where to go and then my esophageal spasming on top of that makes for miserable moments. Hang in there and try not to get discouraged if it takes your Dr a while to figure this out but always be a persistent advocate for yourself! Praying for you.

My ms hug felt like an electric shock when I took too deep of a breath, my diaphragm was having a spasm with every breath.........very painful.
Tell them EVERYTHING and let them decide whether or not it is or isn't related.

Yup, I have them more often than I would like. They can start in my back and move to my front, in my chest area ever down to my waste... sometimes it is so weird because I can almost feel the areas being squeezed as it moves along, as if someone had their hands inside me and start squeezing slowly in one area, then release and move down to the next etc etc.. very strange and at times very painful. I also loose my breath if it happens near my sternum.

Same here like pain that shoots from my back around my ribs or even up my chest. It happens for me in a few different areas.

Yes! Have your neurologist order an upper spinal MRI not just head
