Bumps appearing symmetrically on the body with a distinct itching sensation should be the occurrence of skin allergy, which should refer to eczema, a skin inflammation related to allergies. The patient’s eczema may occur as a result of exposure to specific items, or eating specific items, or having significant allergies themselves. This is a typical clinical feature of eczema, which occurs symmetrically on the left side of the body and on the right side of the body. When this occurs, the patient can apply glucocorticoid ointment topically, which can provide relatively rapid relief. However, patients must be treated in a timely manner because eczema is prone to chronic and recurring episodes in the clinic, which can bring about intense itching and seriously affect the quality of life of patients.
