Emotional healings are almost always long lasting.
This is particularly true if you follow the suggestions in the EFT Course and address the emotional events as specifically as possible. The original problem was addressed too globally and thus only partially neutralized. Physical healings are often impressive and long lasting as well but are more likely to re-emerge than emotional issues. Experienced EFT ers see consistent evidence of this. Thus what appears to come back is simply the same physical ailment reacting to a different emotional issue.
