Hello. It sounds like you may be suffering from hypothyroidism
). Your thyroid stimulating hormone
level (TSH) is elevated, which indicates that your pituitary gland
is trying to get your thyroid gland to produce more thyroid hormone. Under the influence of high TSH levels, your thyroid gland could be swelling (this is called a goiter) and that's probably the source of the lump in your throat.
Hypothyroidism can cause lots of problems if it isn't treated: cold intolerance, weight gain, depression, impaired mental function, heart failure
, etc. I suggest you see your doctor as soon as possible to confirm your diagnosis and begin treatment. (This situation can be corrected by taking a single pill every day.)
I hope you feel better soon!
