HI, I am a 46 years old male, lately i am noticing that my neck and chin are much bigger and my trachea cartilage is wider too. nothing asymetrical , no lumps on on side. also a year ago my prolactin level was 20 and 19 ( repeated in a differet lab ), i saw 2 endocrinologist a year ago for the prolactin at 20 , they said nothing to worry about at this level ; do you think i need to see a doctor now
