I am not clear about what you mean feel the feeling all over--do you mean feel the palpitations all over? Are the palpitations moving around?
Also, just a thought--the Mirena is probably the reason your magnesium, calcium, and vit. D are all deficient. The synthetic progestin does this
One sign of magnesium deficiency is brittle, thin, or splitting fingernails, which I experienced all the while on Mirena and I believe others have stated as well. Since removal, I have been taking magnesium supplements and noticed my nails were stronger within a week.
