I have actually taken these barley tablets, not at all expensive, and they relieve pain and give energy, it's amazing. One testimony there is about a woman with FM who found relief with the tabs.
I had terribly debilitating pain from something they call athlete's arthritis...and still will, if I don't take something. Right now, I eat mostly fresh organic produce, except I got a bladder infection and was eating like lentils and stuff, cooked (2 much is fattening), and usually walk an hour daily, and drink the cleanest water I can.
I'm taking iodine by Lugol's, bloodroot, D3, potassium gluconate, and kelp...just what I have.
The cancer diet I used, would help you with guidlines on what to eat creationhealing.blogspot.com
...and Green Supreme will give you diet guidelines with the barley tablets, too.
If you have a few thousand dollars, yippee, you can get a Kangen water machine, and it will get alkaline water to your cells in a hurry, and heal much of your problems, from what I have read about it.
You can do this, don't give up. That pain is really a killer, I know. Don't let it get you down. Get on the healing path, and you'll be dancing down the road soon enough. Write back if you're discouraged, okay?
Please, Lord, help her in Jesus' Name and for His sake, I pray, amen.
