I just received an email from my friend,
Hopinso. She's having trouble posting messages on CZ right now, and she asked me
to pass this information along to you.
Hopinso said that her eyes also made cracking
noises several years ago. She finally went to
a chiropractor, who told her that "cracking eyes" were a sign that her neck was out of
line.
The chiropractor did some manipulations on
her neck, and the cracking eyes disappeared,
never to return.
Sounds like it might be a very quick and easy
solution to your problem. Let us know if it
works for you.
