I was diagnosed with non toxic goiter when i was 19, doctor prescribed me levothyroxine 50mg but i felt tightening of my throat so i stopped?

Careful SymptomsOnly: clues, far from whole story of what is going on. Goiter (enlarged thyroid) driven by low iodine intake, increased TSH, antibodies which emulate TRH, etc. Levothyroxin only a molecule used as a treatment tool, may help some of the symptoms/issues but does not solve the cause. However, if the tool is working, stopping it may allow problems to recur & increase. Study & seek help worthy your trust.
