What tests are out there to check health/condition of the heart? I have over the last few years been concerned about a mix of symptoms that can relate to ovaries, gall bladder and thyroid. On blood test basis(es), all seem clear. I have had a couple of scans and it seems there is nothing untoward re. liver. I just feel as if I'm a bit crazy, it is quite stressful because there are some days where I feel worseningly awful but have ruled out quite a few areas, seemingly (indeed, I'm to believe they are in good nick). I'm much more relaxed in terms of school holidays than my usual routine which is a big commute but a couple of days ago I had serious shoulder/back aches and pains and sapping fatigue so I can't put this down to being squashed on a train. I'm mid 30s, & worried.
