My dr. has told me that anxiety can affect any part of your body and can cause other physical ailments. Once the anxiety is under control you should feel a little better. Hope this helps,best of luck!
I agree with Slmercer. Anxiety has so many strange symptoms. Are you seeing a counselor or taking any meds for your anxiety? You've had many medical tests done so it sounds like your healthy. I understand the dizzy feeling. Mine is not always quite like yours but I do have dizziness out of no where sometimes. Remar
Honestly I haven't token meds nor counseling since 2008 and it wasn't consitent
I think getting in touch with a therapist and a psychiatrist would greatly reduce your symptoms since you have already had a lot of testing done.
