We'd be able to respond better if you would please post your thyroid related test results and their reference ranges.  What is your synthroid dosage daily?  Since the primary cause of diagnosed hypothyroidism is Hashimoto's Thyroiditis, have you ever been tested for Hashi's?  Those tests are TPO ab and TG ab.  Since hypo patients are frequently low in other important areas as well, have you been tested for Vitamin D, B12 and ferritin?  If so, please post those results and reference ranges also.

Doctors often tell patients that their thyroid levels are adequate, when they are not.  Many doctors have the "Immaculate TSH Belief", with which they only go by TSH results to diagnose and treat a hypo patient.  This does not work. Others will test beyond TSH, usually for Free T4, but then they want to use "Reference Range Endocrinology", by which they will tell you that a thyroid test results that falls anywhere within the range is adequate.  That is also incorrect.

A good thyroid doctor will treat a hypo patient clinically by testing and adjusting Free T3 and Free T4 as necessary to relieve hypo symptoms.  Symptom relief is all important, not just test results.  

What is your daily dosage of thyroid med?  What is the med you take?  Also, please post your thyroid related tests and their reference ranges and members will be better able to assess the adequacy of your testing and treatment.

Im so thankful to read that Im not the only one going through this. I had my thyroid removed in June 2009 due to a nodule that had formed in the centre of my thyroid but I was informed, after half my thyroid was removed, that I have thyroid cancer. Anyway the rest pf the thyroid was removed and Im cancer free but little did I know at the time and thought everything would go back to normal. I also get palpitations that it wakes me up at night and my body shakes as a result. I contacted my specialist and on Monday Im going for a 24hr Holter ECG. Im on bilocor for the palpitations and my thyroid functions have stabilised..Ive got a strong feeling that my thyroid functions are out of balance again. Really trusting for a miracle!!!

Hello everyone,

Yes it is very possible to have heart papls with hypothyroidism!  It may also be aggravated by adrenal fatigue (www.****.org). makes you have sugar and salt cravings.You're adrenal glands have to work extra hard to make up for low thyroid function. I finally found a Dr. who will listen to me and who cares about my health improving. Don't take no for an answer.. You know your body better than anyone else. Listen to your body and if your doctor tries to tell you that you are just depressed and you just have anxiety attacks and panic attacks then find a new doctor because those are all symptoms of hypothyroidism also. Taking a bunch of pills that you're body doesn't need to mask a whole host of symptoms won't help you're thyroid get well. What I've learned so far is to do your research. Watch your nutrition and take needed supplements to support your body. Find a Dr. who will listen to you. It took me 6 doctors to find one that would listen and treat my condition. I spent money out of pocket and now that I have found the right dr. I am hopeful to will recover. Hope is a big deal when you suffer from thyroid disease because most doctors don't listen to you and make you feel wrong. Stand your ground and don't be made a victim. Its not easy to push forward and see the light at the end of the tunnel but you are your own best advocate. A YouTube video I stumbled upon help me on the path to find my new doctor.
