Hi everyone! Need some advice.

So in 2014/2015 (I can't remember exactly), one day, my neck started feeling strange. I felt like it was swollen on one side, so I went to the hospital. I was so afraid, I was going to the hospital almost once a weeks because the right side of my neck sticks out more and feels thicker and bigger then my left. And this really isn't something that has always been there. It had just started.

Anyway, I had sooo many blood tests and nothing was found. In 2015, I had an x-ray and nothing was found. Now here I am all these years later and my neck is still the same. It feels stiff and I feel pressure from the right side of my neck to the back of my head. I have anxiety and it honestly feels worse when I have an anxiety attack or I am stressed but even when I am not, it still feels stiff and it sticks out more then the other side.. it isn't painful. Rarely it'll feel sore just mostly pressure. A new doctor I started seeing said that I possibly carry stress in my head and neck (I get headaches in the lower back of my head).

I was prescribed Valium to take as needed. I have only taken 1 when I had a horrible attack. It helped with my neck as well but once it wears off, I feel the stiffness again. And I really do not want to take medication every time because this goes on all day, everyday. I've tried different pillows, massages, etc. When I go to appointments my doctors always feel my neck and don't mention anything. I am honestly terrified that this could be something serious especially since it has been years. I have kids and I really want to watch them grow so it terrifies me. Anyone have any idea? I've gone to different doctors, hospitals, clinics, etc. I don't know..
