yna,

I just googled about currency restriction into Malaysia.
This it what I found:-

There is no restriction on the amount of foreign currency notes and traveler's cheques
brought into Malaysia by resident and a non-resident, except a few cases which are stated below in the table.


From the table of exceptions:-
No restrictions, excluding banknotes of India, Indonesia up to the amount of INR 270 and IDR 3,000

Here is the source:-

I also checked a couple of other sites and the same information is there.

Please check yourself also.

Now please stop worrying.
Get yourself better from your fever .

Take care and God Bless
