Online symptom diagnosis is correct about one-third to one-half of the time. The One-half of the time is only when the right diagnosis in the top three responses. Doctors are better but doctors are still far from perfect.

Medical error is a major factor in ten percent of all deaths in the United States. A medical study finds that 250,000 deaths per year in the United States are from medical error. The BMJ journal study had a higher estimate than the Center for Disease Control estimate of 150,000 per year.

Internet self medical diagnosis can be dangerous. Online symptom checkers accurately diagnosed symptoms about 34 percent of the time. About half the time, the correct diagnosis was one of the top three options on the list; it was in the top 20 in 58 percent of cases.

Online diagnosis inferior to visiting a real doctor for checkups and tests for a better diagnosis.

CNN Had an Alarming Story About A Woman Who Died from a Brain-Eating Amoeba

The CNN story highlights a danger of the fairly common practice of sinus rinsing. People with allergies get a lot of symptomatic relief from stuffed noses by using a saline rinse of their nose and nasal cavities.

Here a woman who rinsed her nose with a Neti pot ended up getting a brain-eating amoeba which killed her over 1-2 years. They also talked about two people in Louisiana who got sick from a different infection. The CNN article then warns about the symptom of a rash or sore on the bridge of the nose after nasal rinsing.

Nasal Rinsing Does Reduce Allergy Symptoms

Nasal Rinsing works. It makes people who have allergies feel a lot better.

Nasal Rinsing and relieving congestion symptoms can reduce the prescription of antibiotics. Overuse of antibiotics can create bacteria that are resistant to treatment. According to the Centers for Disease Control, every year, two million Americans are infected with antibiotic-resistant bacteria. Of those two million, at least 23,000 people die.

What is the FDA Recommendation on Neti Pot and Nasal Rinsing?

Tap water isn’t safe for use as a nasal rinse because it’s not adequately filtered or treated. Some tap water contains low levels of organisms — such as bacteria and protozoa, including amoebas — that may be safe to swallow because stomach acid kills them.

What Types of Water Are Safe to Use?

* Distilled or sterile water, which you can buy in stores. The label will state “distilled” or “sterile.”
* Boiled and cooled tap water — boiled for 3 to 5 minutes, then cooled until it is lukewarm. Previously boiled water can be stored in a clean, closed container for use within 24 hours.
* Water passed through a filter designed to trap potentially infectious organisms.
