What is level 5? Stage 5? The lymph node is on the same side as my throat pain. I have had 2 Ct scans, a tonsillectomy with two small biopsies which came back ok. I can't believe this is happening, but I didn't see anyone who had clavicle swelling on any of these sites. Wow. I'm so scared, because I have always known this isn't a good place for swelling.
