Does Panic Attack Lead To Abdominal Discomfort?

Hello, About 3-4 weeks ago, I was sent to the ER with breathing difficulties but the doctors could find nothing. They said I was having a panic attack. I felt like someone was choking me and had a tight feeling in my chest. Now I am out of energy quickly and don t have much of an appetite.Additionally, for about a year, I have had difficulty burping, having to twist and turn or even press my stomach area to release some gas.Are these two things possibly related? What is going on with me?
