Welcome to the group, Cassie.
If you must have thyroid disease, this is a good place to come to get help through it.
I wanted to address your concern about non-script alternatives to Synthroid.
I'm a person who loathes Big Pharma and the drugs it peddles ... the ones that are advertised all over the media... the ones that have a list of side effects far worse than the conditions the drugs treat. But Synthroid and the other meds for underactive thyroid aren't like those drugs. The active ingredients are simply the hormones that your own gland would make if it could. They replace the natural hormone you must have for good health. They don't alter your body's natural function in any way - the way that statins or allergy meds or stomach acid blockers do. That's comforting to me; maybe it will be to you, too.
Compared to those 'designer' drugs-of-the-moment, thyroid meds are cheap. My script costs me about $7 a month with insurance. At full cost without insurance, the cost would be only $10. You can't beat that price.
Another thing ~ We who have fought to get diagnosed and treated, and who finally feel normal and healthy again, treasure that prescription like gold. If anyone would try to take my Armour away, they'd be cruisin' for a bruisin'. Once you regain your health through that tiny, cheap prescription pill, you'll probably feel the same way.
This is a great place for whining, great at support... but it's even better for education... For letting you know when your doctor's doing the best for you, and when he's flubbing up. If you read here long enough, you'll see just how few doctors are really successful at thyroid treatment. But you'll also learn what to look for in a new doctor if you ever have the need to switch.
