I can relate to the insanity part. I started thinking crazy, dumping my meds all over the house and falling everywhere. I ended up in ICU for 5 days with an infection in bowel, later diagnosed with collitis. When I got home I started getting Knots and rashes they said due to low immune system. They said I was fine when discharged. Still feel bad, been a month, knots are going away finally. Have your white blood cell count. Mine went to 26,000
Hives, unexplained weight gain, fatigue, affected menstrual cycle, ringing in the ears, heart disease, oedema (fluid retention), peripheral neuropathy, high blood pressure, urinary incontinence, charley's horse, and hallucinations are some of the many listed symptoms of hypothyroidism. Research reported in the journal Dermatology found that the frequency of thyroid antibodies is significantly higher in patients with chronic urticaria (hives) than in healthy controls. The most common cause of hypothyroidism is Hashimoto's Thyroiditis (autoimmune hypothyroidism).
To avoid misdiagnosis, thyroid tests should include - TSH (thyroid stimulating hormone), Free T3, Free T4, and thyroid antibodies - Thyroid peroxidase antibody (TPOAb) and Thyroglobulin antibody (TgAb). Doctors usually only test TSH and sometimes Total T4. This is why millions are misdiagnosed as both these tests can be normal with hypothyroidism.
