I thouhgt my 15 year old son had a hernia, but the Dr. said it was too hard to be a hernia. She set him up for bloodwork & an ultrasound. The bloodwork came back OK, but the ultrasound showed that he had an enlarged lymph node and it showed "thickening". She was concerned tht he had shown no signs of infection, but put him on antibiotics as a pre-caution. She set up a consultation with a surgeon to remove the lymph node. I haven't been given much information, I just know that they want further pathology. I am concerned and would like more information.
