i have a 13mm thyroid nodule

ok so i need some reassurance that this is not dangerous!...i have been feeling constant throat tightness/compression like a rope around my neck for 4 weeks now, i have done numerous doctor visits and no one was able to find anything simply saying it was a sore throat/ or gastric related, until my doctor ordered a neck ultrasound just a week ago and it turns out i have a nodule of 13mm even though in reality its bigger if the doctor was able to feel it with his hands. I am also having difficulty swallowing foods, i am able to swallow in small bites but after finishing each meal i feel the residue in my throat that feeling as if something is stuck. i had a barium swallow test done and the report was the same, stated that dry foods lasted a bit longer to go down and some residue was seen. I have been feeling extremely anxious due to this problem, still waiting on that referral to the ENT doctor for a biopsy. meanwhile i have no clue if this can aggravate my throat compression? waiting more time like this
