Periodicly I have esophagus spasms, pain in my chest and upper abdomen, feeling like a heart attack, with pain radiating into my jaw. I am also hoarse, fatigued, can't sleep, depressed and have thinning hair. My doctor says my thyroid blood tests are borderline and don't require medication Years ago I had a cyst on my thyroid and took synthroid but ran out of money so I stopped taking it. Any heart trouble has been ruled out. I also have stomach spasms. Is it my thyroid? What should I do? Thanks.
