What causes recurrent skin sores at multiple locations on body?
Skin infection is common cause of such sores.
Such recurrent skin sores at multiple locations are generally caused by bacterial infections like streptococcus.
Ideal approach would be to get swab from the wound tested to find the causative organism.
Then specific antibiotic course can be suggested.
Keeping skin dry and clean can help reduce and prevent such sores.
