how do i find a good thyroid doctor who knows that the 'normal' may not be everyone's normal. I think my thyroid is not working properly, my mom almost died and all of her sisters have thyroid issues. I have been tested 2 times - 10 years ago when I first started feeling sluggish and gaining weight and 2 years ago when I was gaining 3 lbs a day and had severe water retention (pushing in my shin a full inch and it wouldn't pop out) ... now I'm having other symptoms (headache, missed period for 2 months when ALWAYS extremely regular, etc). Even though all tests came back as 'within normal limits', I have a suspicion that those normal limits are not MY normal limits. How can I get a doctor to take all of this into account. At this point, I went from 126 to 173 (now) and I realize some weight gain is normal but I am wheezing and heavy breathing and I exercise by walking on my treadmill when I work (sometimes 2-4 hours a day).
