This is a 12-year old's summer essentials for a ride into town - in addition to his iPad. I took our guy to the doctor this morning. He has a large knot toward the back of his neck. He only told me about it at bedtime last night. The doctor said it is a swollen lymph node, and it is his body's way of fighting off infection. (I didn't realize they were so far back). He said it should heal within two weeks. I have to be honest, this Mama was a worried. I'm thankful it was nothing serious.
