The doctor was telling the truth. Don't know what is the
cause.
The bomoh, cannot let the opportunity pass. Must say something
along his line of expertise.
If go to the temple, the medium would probably say some spirit
was offended by them.
If go to an astrologer, it would probably be because the stars
and the planet lined up and is not auspicious with their date of
birth.
some of these stuff do happen in sg, esp for those that need
mediums to resolve them =/
