The swelling of the feet caused by foot odor is actually mostly due to bacterial infection secondary to the breakage of the skin after the appearance of foot odor. And after the bacterial infection, it may cause local inflammatory swelling of the skin. Some may be accompanied by a certain amount of inflammatory exudation and the appearance of erythema, and as the erythema continues to develop, it may form a secondary infection called dermatophytosis or tinea pedis. Anti-infection treatment is needed in a timely manner, usually early after the bacterial infection has been controlled, followed by antifungal treatment. This is because a secondary bacterial infection from tinea pedis can easily induce tinea, which can then further aggravate and even induce sepsis, etc. Therefore, it is important to provide timely treatment for foot swelling caused by tinea pedis to prevent the expansion of the infection.
