Hi,
Boils are skin infections.. Also called
pyoderma.
It is a bacterial infection.. Caused by staphylococci.
Whenever pyoderma occurs, one should find out the preciptating cause.
As you said, there is no apparent cause... But , remember there may be some hidden cause.
See, actually pyoderma occurs due to poor immunity, poor hygine, poor nutrition or some internal diseases like DM,
HIV,
anaemia or other.
I advise you to
consult dermatologist.
He will diagnose some cause after thorough history,keen clinical examination and complete array of investigations.
Then and then , proper treatment will be given.
And he will manage to prevent the relapse of pyodema.
I hope you got my answer.
Thanks.
