a problem doubled?

[light]

hello,
is there a difference between "a problem doubled" and "problems doubled"?

context: a person is having financial problems. afterwards, he also has health and family problems.

now if we want to describe this situation, do we say " a problem doubled" or "problems doubled" (want use the terms as a subtitle in a text)

since the nature of problems is different (financial, health and family) "problems doubled" is more suitable to my mind. what do you think?
or can we say his financial, health and family problems form his personal problems, so it is one big problem?

Hi

I'd say his problems doubled.

We say problems multiply.

(Multiply includes the idea of doubling but has the sense of 'increasing')

[light]

so it's definetely problems?

is double not used or multiply sounds more natural?

[David L.]

'problems doubled': I have never heard it used as a general expression.

problems multiply
or
"mounting problems at home and in the workplace"
or
"increasing difficulties with regard to..."
