Corn removal, where can I go?

Hi

I have a corn on my little toe that is painful and
is causing me discomfort,

It has been there for 6 months, I tried several treatments but the corn keeps rebuilding up and I want to just get rid of it for good.

Can anyone recommend what is the best way to remove a corn and where to go?
  I heard a laser
technique can remove it but is it permanently or not?

Thanks

The most common corn removing liquid in the US, Dr. Scholl's brand, is 17% salicylic acid.  I found some products in Vietnam that contained salicylic acid.  I forget the strength but they were way less and did not work,  as you seem to have experienced.  I had to have a friend bring some from the US.  Unless you can locate a full strength product, maybe better try the laser.  It will be far less expensive than it would be with plastic surgeon in the west.
