I have a FRIEND WHO HAS SIMiLAR SYMPYOMS and the dr. says she has fibromyalgia. She is taking malic acid and a product that trask has with malic acid and magnesium. I am sure there is other brands with malic acid and magnesium. Try this to see if it works, Is your dr. having you take meds for the heart? She is also. Good luck and pray for God to heal you.
