Rick,
First let me tell you, I signed up for this just so I could reply to your post.
I can tell you two things. Number one, find a good doctor. It took me FOREVER, but I found one. I did a ton of research, reading and learning and I found that for me, Synthroid is poison.
My ex-endocrinologist (an MD) diagnosed me with hypothyroidism, but never diagnosed me auto-immune Hashimoto's, she never noticed my vitamin D was way below normal. My now-doc (a DO) diagnosed me with Hashimoto's auto-immune (no one ever told me I had an auto-immune disorder in 30 years!)
My now-doc, the DO, found something else that the MD never found (unrelated, but interesting, this doc is just very thorough in her history and blood work). AND the MD that I had came highly recommended by many doctors I know and lawyers. She is top in her field....go figure.
Number two, my ex-endcocrinologist had me on Synthroid for 5 years and it nearly killed me. I am still recovering over a year later. So be glad you noticed the problems right off the bat, I was an idiot and stuck it out and felt miserable because a doctor refused to prescribe me bioidentical, would only prescribe synthetic and I stuck it out because she is top in her field....so I say, Rick, good for you! You're quicker than I was!!
My AMAZING now-doctor has me on Armour bioidentical thyroid replacement, she had me quit gluten completely and put me on 50,000 IU Vitamin D once a week....I am feeling better every day.
The symptoms I was suffering on Synthroid were unbearable. The inflammation I had was so severe, words do not describe....I diagnosed wtih plantar fasciitis, piriformis syndrome, my hands, feet and face were beyond swollen, it was hard to breathe, it hurt to sneeze from the fluid around my heart and lungs..... I gained 40 pounds, I could not fall asleep or stay asleep.....there are so many symptoms.....teeth clenching, heart problems, I was dizzy, disoriented, I had lost my will to live, basically....I could go on for days telling you symptoms. Years ago I had my gallbladder removed (thyroid) and in my teens I had developed ingrown toenails....thyroid...who knew.....
My now-doctor that I LOVE is a DO, not an MD.
The doctors I had in the past(all MDs) would tell me: "Your labs look great, see you in a year." even though I was miserable.
You want to find a doctor who discusses your labwork with you, GIVES YOU A COPY OF IT and asks you: "Okay, your labwork looks good, but HOW DO YOU FEEL?"
DOs look at THE PERSON, listen to THE PERSON and treat the body as a whole and do not just look at and treat the lab results. So that is my advice....research and learn, it helped me immensely....and find a good doc.....
Good luck!!
