I'm so glad to see that I'm not the only one dealing with this awful disease!
I was diagnosed at 19 with Hashimoto's Thyroiditis and am 25 this year. The symptoms that took me to the doctor in the first place were chills, constantly feeling cold, the feeling of an adrenaline rush in my chest several times a day, hair loss, and heart palpitation. I was prescribed 50mg Levothyroxine and have been on the same dosage since.
Next month I am going back to the endocrinologist and hoping to undergo some more invasive testing as I have been feeling generally unwell on and off for the last year and a half despite my levels testing normal. The worst symptom that I have developed is horrible brain fog - I can't remember words (tip of your tongue feeling), plans or appointments I've made, and on bad days, feel like I can't mentally process anything. I have started to have horrible moodswings that I have been told is associated with a hormone imbalance, as well as found out my prolactin is high (that unless there is a pituitary gland tumor, is caused by Hashimoto's. I've ruled out tumors.) I have been diagonosed with idiopathic gastritis, which I have read can also be a by-product of Hashimoto's because it is autoimmune in nature, and I have also been dealing with potential interstitial cystitis which can be linked as well. Most recently I have started to develop neurological migraine symptoms - dizziness, feeling of standing on a boat, "brain zaps" - and have been wondering if these too could be linked.
I've done my best to eliminate gluten and dairy from my diet, as well as restrict soy. So far going gluten and dairy free has provided some limited relief from my GI and brain fog symptoms, but sadly it's hit or miss and not full proof.
At this point in time I'm wanting to see if anyone else has been having such extensive issues, or ask for advice on what other chances I can make myself, or avenues to pursue with specialists to try and start feeling normal again.
