I have had underactive thyroid for 20 years. Taking Levo and low dose Celexa for heart palps that come when the thyroid decides it will work for a bit. Now in the throws of being menopausal at 49 and exhausted, feel fullness in the neck, night sweats requiring an ark and animals two by two, foggy in the brain and just feel as though I am pushing a piano. Any suggestions? Has anyone else felt like this? Is there a light at the end of the tunnel?
