Not a doctor. i do think that we have a doctor here, so maybe she will see this.

I'm so sorry to hear that she's still struggling with this.

a few thoughts based on my limited experience with medical issues. Can you research this online and find a specialist that seems to have more experience that the issues. You may need to go out of town. try looking at doctors within a three hour drive. Then contact that doctor's office and tell them that you want to see them and need help getting the referral.

You'll probably need to investigate your insurance. you may be able to call the Human Resources Person at the business that provides the insurance and ask their help.

Can you try going to a new Primary care Doctor for a second opinion?

Isn't her doctor someone who rides with her?
