On one side of our body, the blood flows TO the heart; one one side of our body the blood flow FROM the heart. In energy/rock healing/protocl the object with the energy (rock, crystal, other person, whatever) is ALWAYS held in the left hand (for absorbtion), the 'output' is always through the right.
I don't think you need any 'therapy'; you're perfectly normal! :)
What happydog said is true:
>>>Also, the left hand has better circulation than your right, that's why wedding rings are worn on the left hand. The blood flow returns quicker to the heart.<<
