I lift up your father in prayer...the Lord often allows these things to show us things we need to correct and balance in our lives...He is kind loving and gracious in that way. I pray that God's healing hand will be on your father and that He will give him all knowledge necessary to be made whole. We pray for God's grace, mercy and healing for your dad in the precious name of Jesus...

I concur with the suggestions of Penisse and I want to add that I have posted a lot about utilizing 20 Mule Team Borax. I hope people diligently research this before discounting it's usefulness and cost effectiveness. There is much annotated research and a booklet entitled "The Boron Conspiracy"...but as always one should use discernment and their own intelligence when studying to discover truth on any subject. Boron tablets can certainly be utilized to remedy the pain of arthritis/inflammation/injury....

Another thing to keep in mind is that there are different forms of magnesium and they each have different effects on the body. Magnesium glycinate is specifically for cramping but some people prefer blends that incorporate several different forms. I use this form for nocturnal leg cramps. There is great research online with Dr. Berg and entire videos on the different forms and their uses. It is worthwhile research. God bless your family.
