Pardon me for reviving this thread, but it felt better than creating a new one, and would help others too I think since the messages posted sound useful.

So are we supposed to Not use sword fingers on people's heads if we want to heal them with this technique? Like if my sister is having some pain around the eyes/sinus or headache, I should not work on that area with the sword fingers? Is it dangerous to work there or it's just not useful? I tried it on some family members so I am a little concerned now.

I have both level I and II, but haven't moved to Level II yet so I don't know what techniques are there yet. I am comfortable with Level I but I will wait a little before starting level II.

Also, what "symptoms" is Sword Fingers good for?
