Healing in of itself can be done many ways, runes, crystals, but the way we will be focusing on in here is using energy to heal yourself energetically.
Energetic healing can also be done many ways, so I advice you to experiment and work on methods that you think will work for yourself better, because there is no real limit of the possible ways to heal.

There are a few things that should always be done in each method though as they are the things that are important to keep in note.
First off, ALWAYS heal from the inside out, if you don’t you could literally leave foreign energy in these, constructs, etc, it's much like physical healing, you don’t want to leave crap in there. Another is ALWAYS use energy that isn’t foreign, use your own energy or energy adapted to you to heal as it is the best to heal with, for the same reason as “inside out”.

Healing “Psi Ball”:
This first method itself isn’t that efficient and should be developed quickly, This method you create a psi ball and instruct it to send energy at the wounded area, give it numbing properties, and tell it to start reconstructing the area with your energy. This isn’t nearly as good as the following method.

Healing “Palm”:
This is my personal favorite, it is similar to the above, but instead you hover your energetic palm (Or physical palm), over the energetic damage and start using that as a focal point to reconstruct the wound, much similar to the healing psi ball but more efficient and direct.
