Patient discussion about organ

Q. i'm going on an organic diet for fibromyalgia does anyone know if this will help this awful pain

A. Couldn't find any research proving that organic diet improves fibromyalgia. On the other hand, couldn't actually find a research that contradict it (or even dealing with it), so no one can give you any established answer for your answer, so it's your decision.

Anyway, remember to consult a professional (e.g. a doctor) before you start any diet or any other intervention.

Q. Can a Chiropractor tell if your organs are shutting down?

A. She told me that because my spine is out of line so much, that it's causing my organs to shut down. I have been having bladder problems. I really think she is just trying to scare me.

Q. I'm looking for natural/organic ways to deal with carpal tunnel syndrome. My Boss has Carpal Tunnel syndrome. I'm looking for some natural remedies to help her ease the pain.

A. I have found that MSM (GNC brand) 1500mg per day works for me. I talked to an Orthopedic Surgeon asking him why it works... he said "they really don't know why it works, but it works for many of my patients". When I stop taking my MSM the symptoms return so it is not a cure.

I have tried other brands of MSM and found the GNC brand works the best for me. It takes about 2 weeks to begin to see the results and several more weeks to get the full affect.
