The prevalence of gout has been high in the last decade or so. However, there are relatively few rheumatologists, and many hospitals do not yet have rheumatology departments. Most of the current physicians of various disciplines, middle-aged and above, did not receive rotational training in rheumatology and immunology during their residency stage back then, resulting in an innate lack of knowledge about gout. They only know that gout is associated with high uric acid, and they only know that gout is associated with joint pain, but they do not know the differential diagnosis of joint pain. Many doctors will check uric acid when they meet with joint pain. And “joint pain + elevated blood uric acid” is often diagnosed as gout. In fact, “joint pain + increased blood uric acid” is not necessarily gout! Two questions arise here: If the blood uric acid is high and there is joint pain, why is it not gout? What kind of joint pain is gout? Hyperuricemia is very common in adult men. And joint pain is also common, and joint pain can have many causes. Various types of joint pain often occur in the same person as hyperuricemia. Therefore, the probabilistic overlap of “joint pain + increased blood uric acid” cannot be diagnosed as gout.
