Not sure. But mine seem to go on for a while, the same. In fact, I went though a period a few years back where I was having the issue over and over again. It did actually improve due to diet. But recently it has come back full throttle due to changes in diet and marijuana. And I realize how hard it is to really explain to others when your symptoms seem so different. Most times a flu has a fever so people think you will have some legit tell. But if you have a panic attack that acts like a fever.. all you have is subjective feeling like poo.

Thanks.
