You are welcome. Physicians have given me back my life several times with excellent surgeries and medicines. I would not want to do without them. Medical "opinions" are borne of a great deal of study, research and experience. Why do you take the FDA with a grain of salt? The biggest problem is that they cannot do their job due to a lack of funding from the anti-science people in Congress. Many scientists are leaving the U. S. because of a lack of funding and giving their expertise to other nations. The internet is a great source of information, but also misinformation. There are an awful lot of "health counselors" and quacks selling their brand of "miracle" cures. It is best to educate yourself with the science and not the woo woo magic. I hope with good nutrition and exercise that your wife will soon feel better. If not, then a thorough physical exam with tests is in order.
