Success stories can be very beneficial for people suffering with things that regular doctors and most of the public tell you don't exist. Especially when you struggle to to feel better--it is nice to see the light at the end of the tunnel. Keeps up hope.
Some say the mind is one of the most power healers. That if you believe enough, your body will do the healing--similar to the placebo effect.
So I don't see anything wrong with wanting to know how others are doing on a particular treatment plan. Keep up the positive thinking, when illness and doubt start to cloud your mind.
