I have been on levothyroid for about 10 years and thought it was under control until my most recent blood test. My MD says normal is between 0.4 and 4.0. Mine came back at 32. I have been feeling really tired, have gained weight (but atributed that to quitting smoking) and have dry skin (attributed that to winter weather). I have had swelling under my jaw and in the neck just above my right collarbone for about 6 months and thought nothing of it. Does not hurt, just uncomfortable.
I had a thyroid ultrasound today.
Should I be worried? Could this be cancer? What can I expect next?
