Patients who develop leg fever can be advised to take their temperature first. Sometimes patients may feel their leg fever when they develop a fever or a slight increase in body temperature, which can cause a generalized fever when the symptoms worsen further. So, you can take the temperature first to see if the fever is caused by a cold or some infection, and just choose oral medication to treat the symptoms. The skin of the body can dissipate heat, and when there is an increase in heat, the heat will be discharged through sweating, but the thighs are not the main part of the body to dissipate heat. The main heat dissipation areas are in the areas of the body that are rich in sweat glands, such as under the neck, head, armpits, and inner thighs. If the leg fever is accompanied by localized redness, swelling and pain, it should be considered as a result of infection, such as dermatitis, gout and other diseases. In this case, you need to go to the hospital in time to improve the relevant examination to clarify the cause of the disease and take appropriate treatment according to the cause.
