Viral cold infection. The area as well.

Hello Docs, hope u all r good I am suffering from viral cold since 3 days, most of the symptoms are now subsided except cough and bit of nose running. However since few days just side of my throat I felt a very small bean shaped inside my skin, I touched it and it was moving inside. But no pain and no swelling, neither it's visible from outside. I really got scared bcoz when u google lymph node it's all about lymphoma. So I went to my GP today and informed him about the same about feel of lymphnode just near the throat area, he touched the area and said it's nothing, it does not feel like a lymph node, it's simply nothing. My only question here arise is when I touch in this area is that the normal artery I felt or may be this has happened first time and I got anxious. I trust my GP but at times secondary opinion is always appreciated, please help, I have attached the pic and marked down the area as well.
