Hi there, Welcome to HealingWell. Your sx could well be anxiety related but I think it is important to continue to follow up with the physicians.
Have you ever been tested for Scleroderma or Lymes? You have a mixed bag of sx so I can see where it is tough to decide which way to look for the cause.
I am not a physician so I am just tossing out a couple of things that come to mind however your sx are atypical.
Can anxiety do this, IMHO yes the mind is a powerful thing and the physical sx can be just about anything.
I hope you are able to back off a bit on all the demands on your life and put your health first.
Again a warm welcome to HealingWell.
