There is absolutely a correlation between emotions and the body. I used to be abused when I was a kid so at 15, I got stomach spasms. The spasms were totally brought on by my stress. Also I got IBS from stress. Our body is like a shock absorber when it comes to emotions. everyone takes it in different parts of their body. Some people get headaches or migraines. That is why so many doctors are willing to disregard people's complaints. They chalk it all up to stress or emotions.

I like this article, especially.
