The gist: avoid the drug-company financed, poorly written, overly hysterical WebMD for the sound information at the Mayo Clinic’s excellent site, including their Symptom Checker.
If you’re looking for the name of a new pill to “ask your doctor about,” as the ads say, the Mayo Clinic Health Information site is not the place for you. If you’re shopping for a newly branded disorder that might account for your general feeling of unease, Mayo is not for you either. But if you want workaday, can-do health information in a nonprofit environment, plug your symptoms into Mayo’s Symptom Checker. What you’ll get is: No hysteria. No drug peddling. Good medicine. Good ideas.
