If you have fibro and are a caregiver(or are caring for a fibromite), please check into using SlowMag. Itnis a magnesium supplement at Walmart(and I am sure other stores). Do not buy regular magnesium vitamins that is among e other vitamins. It does not work. It is not processed they the digestive tract and therefore, not useable. It has to be SlowMag. I truly feel better since I started it. I take one a day. It has magnesium and calcium, which has to have the correct ratio, for your body to use it correctly. Also take Epsom salt baths. The magnesium in the Epsom salts soak into your skin easily. I have only been doing this for about two weeks and I have noticed a difference in the soreness of my muscles. Not the deep muscle pain, but the general, light soreness. Give it a try. Hth!
