Hello and welcome to hcm.
I have read your question and i can understand your concerns.
If i were your treating physician i would have done physical examination such as blood pressure,tremors,sweating,proptosis,thyroid exam to ascertain any lump and to ascertain
hypothyroidism or
hyperthyroidism.i would have asked about weight loss,feeling of warmth or cold,diarrhea ,weight loss,anxiaety and depression.
For the thyroid nodule i would have done fine needle aspiration cytology or excision biopsy to ascertain whether it is benign or malignant .
For thyroid malignancy surgery will be done with or without radiotherapy or chemotherapy.
Hypothyroidism will need thyroxine tablets upto 150micrograms with regular
thyroid function tests.
Hyper thyroidism will need carbamizole or methimazole.
I would suggest you to meet
endocrinologist and a
general surgeon.
Meanwhile remain calm.
Thanks.
Hope the answer is helpful.
Regards
