Swollen lymph node venting

Is it normal for the Dr to google lymph nodes at your appointment? I felt like I got no answers to my pea size lymph node on the back of my neck. She just told me to keep eye on it which last two days it’s the same and doesn’t bother me and it’s soft. I do have couple sores in my scalp and I think I have little allergies but not sure if that causes it.
