Sometimes my legs and knees always hurt when it is windy or rainy. Who knows what the problem is?

It should be rheumatoid arthritis. The word rheumatism originated in ancient Greece. In the 4th century BC, in the article on human anatomy in the Complete Works of Hippocrates, it was believed that rheumatism was caused by the influx of body fluids into limbs and internal organs due to dampness and cold. China's Huangdi Neijing (5th century BC) also called the mixture of wind, cold and dampness joint pain. Because rheumatism mostly involves joints and causes pain, the word rheumatism has been used ever since. With the development of medicine, people have a deeper understanding of rheumatism. In fact, rheumatism is a systemic disease, mainly involving connective tissue. Most patients have joint and muscle diseases, which are related to immune abnormalities. It belongs to autoimmune diseases, including many diseases, such as lupus erythematosus, rheumatoid arthritis, dermatomyositis, Sjogren's syndrome, scleroderma and so on.
