dear friend,

i just sent you a rather lengthy response, but was lost in cyberspace, somehow, somewhere. i do not wish to write this again, so...

Answering your questions top to bottom...

1. NO
2. NO
3. YES, definitely a spiritual one, but nothing to be afraid of physically. However, when in doubt, ask you body.
4. YES, when your intention is pure, healing will always occur.

sorry for the shortness of the response. i'll see if i can fish my other answer.

sincerely,

flipstick
