Hello Annu, Your son may have dry skin that could be eczema but the boils is secondary to infections with a common skin bug called staph aureus. If there are any boils actively bursting, a pus c/s or swab will identify the mechanism. Antibacterial creams such as Fucidin are helpful against such bacteria and Mupirocin cream 2% nasal oitment to eradicate carriage and chlorhexidine soap to wash the whole body is recommended. Please get in touch with your doctor to see if this is feasible. Children s skin are sensitive to insect bites, and the same cream will help (Fucidin). Thanks.
