1. Eliminate infectious factors Since ringworm is mostly caused by other ringworm diseases of your own, it is important to treat ringworm in other areas, such as ringworm of the head, ringworm of the hands, and ringworm of the feet, at the same time as treating ringworm of the body. It is also important to avoid contact with other people or animals with ringworm, otherwise ringworm can recur due to reinfection with fungus even after treatment. 2, adhere to the correct medication Many drugs can treat ringworm, but some patients change all kinds of drugs but still can not cure it, mainly because of improper methods. It is easy to treat ringworm with topical medication, but you must insist on applying the medication 2 to 3 times a day, and the scope of the application should be slightly larger than the area of the skin lesion, and you should insist on it for a while even if the rash subsides and itching is not obvious. Do not fish for three days, as if the grass is not eradicated, the condition can be temporarily relieved, but encounter the right conditions will be the spring wind blowing again. 3, avoid using corticosteroid ointment That is to say, you can not apply hormonal drugs. Corticosteroid ointments such as skin relaxation ointment, dexamethasone ointment, betamethasone ointment and some herbal ointments containing hormones can be used for many allergic skin conditions such as eczema, contact dermatitis, and neurodermatitis with good results. However, ringworm is caused by fungus, and hormones cannot kill the fungus, but instead can promote its growth and reproduction, making ringworm develop faster and more seriously. This is why topical medications should not be abused at will either. If ringworm occurs due to low body resistance caused by some systemic disease, it should be treated actively to strengthen the resistance. If ringworm is caused by long-term use of corticosteroids or immunosuppressants, these drugs should be used as little or as often as the condition allows. If the rash of ringworm is widely distributed, you can use internal antifungal drugs such as ashwagandha and ketoconazole, in addition to topical drugs. However, these drugs have certain side effects, such as liver and kidney damage, and should be taken under the guidance of a doctor, and the liver function should be checked regularly during treatment.
