Toe fever may be localized to the area where gout exists, especially if there is drinking beer, eating seafood and a lot of soy products. In addition, it may also be nail fungus or purulent dactylitis. Observe whether there is local redness, swelling or discharge. The doctor will make a preliminary judgment with the physical examination. If gout is considered, uric acid measurement can be completed. The doctor will make the appropriate treatment according to the condition of the test. After confirming the gout, you can apply febuxostat to lower uric acid, and local area can be topical magnesium sulfate. If it is a nail fungus, trim the nails, disinfect with iodophor and anti-infection treatment with Bactrim. In case of severe nail fungus, antibiotics should be administered and local nails should be removed.
