I agree with Rick about the leg being about stepping forward...that's often one that i see and experience at times (though for me, it's usually injuring said ankle/leg or tripping, lol)
also, what Howler said about us all having the capacity for healing. Healing is an essence, and energy that is available to all...some use it and apply it daily or in working with others, some tap into it only when needed. I also think it is tied to a sense of empathy and compassion, which we all have.
As we develop our higher selves and the ability to hold more light and vibration, i think we will be more apt to easily align with healing...and that can mean just hearing our inner voice that tells us when to soak, when to rest, when to eat and what is healthy...etc.
hope that makes sense!
oh - also, here's a tidbit from my Lightworkers class we practiced:
of course when healing we take a moment and ground and open. The way I was taught is to basically 'become a channel' for the golden light to come through... it pours in through the top of the head like a shower, and just flows from shoulder down the arms and out the hands... (we don't hold any of it, but of course you get a healing whenever that ray of light is activated and passing through your own cells as well.) One of the techniques was to just use the index and middle finger (folding the rest in), like a concentrated beam, especially works on migraines and specific locations/injuries.
hope that helps!
