I'm hoping maybe someone who has been through this might be able to give me some insight. I'm 29 and normally healthy but for the past several months I have been experiencing increasingly bad anxiety that I cannot explain. It started with panic attack like symptoms that would come and go, then got to where the smallest stressor would put me into meltdown mode and now I basically constantly feel on edge, even when home "relaxing." This by far has been my worse symptom, but also I have various other symptoms, some of which seem to for hyperthyroidism and some that don't... I have a consistently rapid pulse but my blood pressure is normal, I wake up multiple times each night, I have slight hand tremors and increased bowel movements. But then again these are also general anxiety symptoms. I have suddenly warm hands (I'm pretty thin and normally struggle with feeling cold all the time), but I wouldn't say I'm burning up or very sweaty at night. I do get a burning sensation on one foot/shin. Anyway, in the beginning of November I got a large sore in my mouth ( I don't know if this was coincidence or not but it's never happened before)and by googling it I saw a possible cause is B12 deficiency. I'm a long-time vegetarian, so that explanation seemed to make sense and it said B12 deficiency can also cause anxiety. So, I asked my dentist for a prescription to do a B12 test and she ordered the basic full panel. My B12 levels came back low normal, slightly higher actually than my last exam two years ago, but we noticed my TSH was down. In 2014 it had been 1.3, in 2015 1.2, in 2014 I wasn't tested, and now it was .7 at the beginning of the month. My dentist of course isn't an expert on this, but she did think the drop was "odd" and referred me to an endocrinologist. However, that appointment is only next Friday And I've already been waiting over a week, with increasing worry. First off, I'm not certain I have a thyroid problem, given my TSH was low normal and my T4 normal (T3 wasn't measured). However I did read online that fasting can artificially lower TSH results and I had to fast for the blood test, so maybe my non-fasting levels are slightly lower. But I see people online saying they are .05 and lower, so I don't know if i could be experiencing such severe symptoms with a level on the very low end of "normal." But then again, I have seen people say optimal level is 1.8, which I am way below, and maybe my body is already responding to the dropping level of TSH, even tho I'm not technically hyperthyroid yet? I just don't know. Also, I've been noticing one side of my throat where i think the thyroid should be seems a bit bigger, but it isn't a visible lump- you need to feel it- and I asked my husband and he thinks it feels slightly bigger but said maybe it was always like that, since like I said it looks normal. Does anyone have experience experiencing bad anxiety symptoms with TSH levels closer to .5-.7? And if so, what did your Drs suggest? Did it work? I'd really appreciate any insight.
