What does it mean if your left palm itches?
Some people say it means good luck or you're going to get some money
Generally your left hand itching means money coming into your life, unless you are left-handed in which case it means money going out of your life.
I thought it was the right hand brings money and the left hand your paying out money.
It means something is irritating the skin of your hand.
It means you are too superstitious or that you are having bad luck
There's an old superstition that when your palms itch it means money. An itching left palm means money to be paid out, while an itching right palm is money coming in. To stop the left palm from itching, the superstition says to rub the palm on a piece of wood.
There may be something to this old tale, since itching palms often show new internal energy moving through the hands. The left hand is the passive or receptive, and the right is the active. When the left palm itches, look for new energy or services coming into your life - Of course this will probably cost you some money. The right palm itching means energy or services going out - Work you might get paid for.
Touching or rubbing wood is a very old method for transferring or releasing unwanted energy buildup (thus expressions like "touch wood"), so if your left palm itches, try rubbing it on the corner of a table - If you don't get a splinter, perhaps you'll save some money!
