Synthroid and heart problems

Would like to know if anyone with side effects to Synthroid, have at any time been diagnosed with Sarcoidosis(inflammation of the lungs). I only get symptoms(read other posts) when taking Synthroid, not other thyroid meds. Please reply a.s.a.p.

I was born without a thyroid gland so I can't compare the way I feel now to the way I would've felt with a thyroid. I've been on Synthroid my entire life (22 years), and I'm up to 112 mcg now. I am very skinny (5'5", 104 lbs) and feel constantly fatigued no matter how many hours I sleep, what I eat, and how much exercise I get. I periodically get pain in my hip joints, heart palpitations, and intense mood swings. My thoughts race but I have very little physical energy. I feel restless and gloomy almost all the time for absolutely no good reason. My doctor tells me I'm depressed but I honestly have no reason to be depressed and I wish she would see it as a symptom instead of a diagnosis. I graduated from a good college, I've got a job I like, I have friends, I enjoy life and my hobbies, yet I feel overwhelmingly sad. This does not seem like depression to me.

I find that after I do aerobics I get a tightness in my chest, which makes me worry about my heart, but again my doctor doesn't seem to think this is cause for concern. I have been irritable/fatigued for YEARS and I suspect I'll feel this way for the rest of my life. The worst of it started when I hit 16 years old and started the 112 mcg. My tests are always normal and it frustrates me that my doctor disregards my symptoms. I've tried other doctors, but they always send me away with my 'normal' test results. Can anybody help?

I have been taking synthroid for 13 years. Had heart palpitations and irregular heart beat - ER dr put me on heart medication. I am seeing psycholgist for anxiety. He suggested that medication can contribute / cause my anxiety. Was doing research on-line for side effects and found this website. Good to know others have had similar side effects. I doubt I need to be on the heart medication since it seems that the synthroid may be the reason for the heart problems. Is there another thryoid med out there for hypothyroidism? All the dr told me was that it is a synthetic form of what my body normally produces - I had no idea it could have side effects or even contribute to other problems!
