I agree go get it checked. Once I had 2 swollen ones on my neck, about a year after going through breast cancer treatment. The Dr. told me that if they were soft and moveable, it was just the aftermath of a cold or some virus I didn't even know I had. If they are hard and don't move- it's not nothing.Anyway, the peace of mind is worth the 20. I was so scared, I had dh leave work and have an emergency appointment. Another hypocondriac here.
