lilyann here, i am trying to wrap my mind around these t-3 and t-4, tsh, and thyroglobin. maybe if i can slow down on all these dr. appt's. i can zero in better. yes, i am making excuses for this octogenerian. lol. truthfully it is hard and i have had this last blood test done on the july 11 and still have had no call from the endocrinologist to tell me what's what. she did say however how she needs to clone herself. so i am guessing its not a very easy job spreading yourself amongst patients. my sister who is an RN, said how she appreciates the knowledge they have to have. not an easy job for sure. your mentioning about "histamine" i have been itching for years 2007 to be exact, called atopic dermatitis, eczema, lots of names and even venous, where the blood vessels in the legs look like they are going to swell and bust, so i had endovenous ablation and guess what....didn't help. just had the barrium swallow last wednesday....said it was ok except for the holding of food further down the esophagus. the ENT said i had a problem with my epiglottis not closing fully and i could aspirate. last december 2022, when she looked down my throat said my rt. vocal chord was paralyzed, didn't say anything about the epiglottis then. i am trying to put the puzzle together. then jan and march of 2023, had the 2 thyroid surgeries. the right side was a radical dissection. lots of cancer removed. so here i am, still trying to read and learn from all of you. wishing everyone the best. take care all on this journey of life. lots of pebbles in the way.
