Why does the toe joint ache when the weather is hot?

There are many reasons for foot swelling. If the foot is swollen and there is no other discomfort, it may be beriberi, which is caused by the lack of vitamin B1. As long as it is properly supplemented, it will be fine. If your feet, especially the big toes, feet, eyes and knees suddenly become red, swollen and painful, and your joints get hot, you almost jump with pain even once, which may be gout. The main reason is that uric acid in the body is too high to be excreted from the urethra or stool, so uric acid travels all over the body, and most of it enters the joints, causing inflammation. Prevention methods should start with diet and avoid eating fatty and high cholesterol foods and animal offal. If your joints are often swollen, and you feel indescribable pain and inconvenient to move, but the swollen part is not depressed when you press it, it may be rheumatic swelling. The causes of rheumatism are complex, which is simply caused by long-term deficiency of qi and blood. If you gently press on the heel and instep, the swelling will be sunken, and the muscle will lose its elasticity, that is, edema. The cause can be renal function decline, so that water can be stored in the body and cannot be excreted. Hydropnea (that is, water leaks from blood vessels and accumulates in the lungs, affecting breathing) can also cause edema. In addition, if liver cells are widely necrotic and form cirrhosis, it will cause other diseases, such as ascites, that is, water accumulates outside the intestines and cannot be absorbed. People with ascites also have swollen feet. If the functions of kidney, lung and liver are abnormal, they often interact with each other and have serious consequences. The above are just some causes of swollen feet. Everyone's physique is different, so we can't generalize. No matter what causes the swelling of the feet, it shows that the body is very weak. It can be said that the alarm has sounded and must not be ignored.
