There are many different traditional and alternative diagnostic methods available to you depending on your illness and the extent of that illness in your body. Of course, the least evasive a diagnostic tool can be, the better it will be for you, but you will need to weigh the benefits of the information the tests will provide against the risks of the tests themselves.
I have compiled a list of the diagnostic methods I explored, many of which I did have. The best advice I can give is to do your homework, research your options, talk with your healthcare providers (traditional and alternative), and talk with your family and friends. It will ultimately be up to you to be your own advocate for your health and healing experience.
