Have you tried alkalizing? I have weak adrenals and I too had burning skin (though no electricity feelings) suffered for a long time until I discovered alkalizing. Most of all calcium, sodium and potassium have really helped. I drink potato juice and boil the skins to make a nice mineral broth. I use ground up eggshells for calcium because it contains trace minerals to help with absorption. I think your symptoms are mineral deficiencies, potassium deficiency can cause the pounding heart for me, potassium can also help lower/normalize blood pressure. Have you tried taking some electrolytes-these can help with absorption of minerals. Please give natural remineralizing/alkalizing a good try, sounds like you have suffered long enough! Go to the Moreless forum to learn more, alkalizing has enabled me to function and sleep. God Bless!
