Hi Dam,
You should take a look at the ES Doctors list & choose a doctor from there to have address your symptoms. A CT scan will be the best diagnostic tool.
Here is the link for the US Doctors List: US Doctors Familiar With ES, 2019
You can use the magnifying glass icon to search for the doctors in your state by name. Posts where they are mentioned will come up.
I hope this info will lead you to a diagnosis one way or the other.
