Like so many of us the Drs couldn't help you despite all their tests and experience. I was lucky that an ND gave me some of Dr. Hulda Clark 's books about 20 years ago. She described a plan to improve health and advised herbs/supplements for various health problems. She and other responsible health practitioners found that killing parasites, and using various cleanses and detoxifications improved digestion, immunity, liver and kidney function and more. In these programs Drs have their role in ordering lab tests and monitoring the body systems. Many people find that these programs will lead to better health over time. Some problems require special treatment - Lyme Disease is one and some underlying problems may have to be addressed. As a person starts to regain their health they are more able to make better decisions about what to do about lingering symptoms. Your Dr can test you for Lyme Disease and Gluten Sensitivity and dealing with either of those common problems will improve your ability to resist infections by parasites, bacteria and viruses. This is the holistic approach which I found so helpful when I was ill.
