wWeird problem?

i feel desperate bring clothing that rubs my neck? when seen with round neck shirts a little tight around my neck, i have to pull it away my neck specially if I'm sitting, the unique t-shirts that I can wear without me cause some discomfort are called polo shirts or buttons is a little ajar neck or dress shirt buttons. I remember back 10 years ago did not have that problem. i hope someone also have this weird problem, or know the name of this problem.
