Clinically, inflammatory nodules may show different clinical symptoms depending on the degree of infection. If the degree of infection of inflammatory nodules is mild, it may only show local redness, swelling, pain and mild increase of skin temperature. At this time, if the external application of vital iodine and oral amoxicillin capsules are given in time, the infection symptoms of inflammatory nodules can be controlled more quickly. Second, if the patient’s inflammatory nodules are less infected, accompanied by the formation of local abscesses, this is often accompanied by a significant increase in local skin temperature, limbs with obvious swelling, pain, limited activity and other clinical manifestations. In this case, the patient needs to perform abscess incision and drainage as soon as possible, strengthen intravenous anti-infection treatment, and after the local inflammation is completely controlled, the clinical symptoms of inflammatory nodules can be gradually relieved and will not cause more serious effects on the patient.
