You know, that is wierd you said that!! I was just telling my husband the other night that my heart felt like it was really burdened these days, like when you run real hard and your heart labors and pounds... Hmmmmmm..I have been checked pretty much and "I" seem to be okay...
Time for you to investigate!! Let the doctors know right away, sure. I bet though, it is like any poor heart that has to go through what we do... You're best to just calm down and let them check you out.. You could just be upset, tired, fatigued or you may just have some condition totally not involved with FM. Who knows?
One thing is sure, don't panic... It'll be just fine, just go get checked out...
Let us know, okay? I will be waiting to see a post from you saying you had a checkup.
Lisa...
Ps...Praying too!!
