There is an upcoming webinar geared toward heath care providers. You should check this out and hear from experts on these illnesses https://us06web.zoom.us/webinar/register/WN_dWcT_XOtREK_aVmCe9lY8Q#/registration
Seriously learning about ME and POTS and even simply validating the patient's experience can change their world. If you know of any physicians or health care workers maybe share this link with them too.
I also recommend Bateman Horne Center's videos on PEM and other subjects.
