Hi @amtxo1989, I know this reply is late in coming but I have read all your post and they are very similar to me. I had hypothyroidism and now I have Hashimoto thyroiditis. I will share with you that I went through 5 regular doctors and an endocrinologist. They only prescribed me levothyroxine and my dosage kept going up and my symptoms kept getting worse. But…there is hope. I too had vertigo, I was prescribed Valium and it helps, however, since my thyroid is working, I have not had to take that in about 2 years. I went to an otolaryngologists and he prescribed that for me, he also shared they are doing studies and are finding a connection with vertigo and hypothyroidism. I also had internal shakiness, and mood swings, I happened to mention this to my OB GYN and he recommended B6 and it worked like a charm! I will also mention that the internal jitters was my 1st symptom of hypothyroidism. I also had heart palpitations, which my internet said was SVT, I was fortunate to have a RN at my place of employment that when I had episodes, out of nowhere, she would take my pulse rate and blood pressure, I eventually got to the hospital in time for them to catch the episode and went to heart surgeon for an ablation surgery, I have not had an episode since. Now, different symptoms kept coming, my meds kept going up, finally after lots of reading I knew I wanted to get on a dedicated thyroid medication. I found a functional/integrative nurse practitioner and she did thyroid test that that includes your antibodies and your free T3 & 4 and that was the beginning of my getting better. She put me on a dedicated thyroid medicine (Nature Throid) along with my levothyroxine and my levothyroxine dose went from 150 to 10. But the best thing she has done is taken blood test that normal doctors won't. Micronutrients blood work should be a must for everyone, get you vitamins and minerals checked. You will feel so much better. I want to encourage you to read and advocate for yourself. Thyroid affects ALL our cells. Keep searching for what works for you. I was low on several vitamins and minerals and my hormones were out of whack as well,. Our health is part of life and a lifelong journey. Please, find a functional doctor or nurse practitioner, get the proper blood work, they will help and you will start to feel better. I still have my MD who I see once a year, for a second opinion, she loves the blood work my NP does on me and says keep doing what works. Hope my story helps you.
