That's impossible for us to say, Jenster. Some doctors even think CFS and Fibro are two sides to the same syndrome..you very well could have it...
about
the fear with your heart - of course, sometimes that's justified, but let me tell you my story:
I used to have that fear in spades. I'll get slight chest pain, lightheaddedness, pressure in my head and arm....(the symptoms they tell women not to ignore.) Twice, I thought I was having a heart attack and headed to the ER, where I was kept overnight and given a nuclear stress test the next day...the 2nd time I almost left, but the dr on duty assured me that if I were his relative, he'd recommend it, so I stayed. My heart checked out fine, thankfully.
Later (after the 2nd one), my own doctor said he wished I had run it by him - he would have told me I didn't need it, because I'm low-risk. And because one of those tests give you as much radiation as you'd be exposed to in 20 years just living on Earth!!
The 1st time it seemed to be related to a non-functioning gallbladder, the 2nd, who knows....I do get Tachycardia at times, but now that an EKG found it's a benign type, I just grin and bear that.
I now know that if you show up at the ER complaining of any kind of heart symptoms, they have to run you through all the tests available (or at least offer them to you.) I definitely think it's a CYA situation.
