Wow PN, , sounds scary.

My DS1 had swollen lymph nodes at the base of the skull behind the ear. They were both swollen and he also had like a wort/lesion on his head that came out of no where as well. We were also sent off U/S and blood tests. It came back his body was fighting a virus and his white blood cell count was high. This was causing is lymph nodes to enlarge.

It was very scary indeed...hope you get results today.
