On Thursday Feb 9, 2017, I took a nap and woke up about an hour later and woke up with a swollen lymph node on the right side of my neck. I didn't think anything of it, so I didn't go to the doctor. Yesterday, Feb 10, 2017, I noticed it was larger and it hurt, especially to touch. I went to the doctor and she said it was just the node reacting to a sinus infection I have. She prescribed me Azithromycen and told me to take Advil cold and flu as well. I did when I got home. I went to sleep and I work up this morning and my same lymph node on the side of my neck is SIGNIFIANTLY larger (double the size, maybe) and is hurting my jaw and ear. I'm not sure what is wrong? I have looked at lymphoma and the swelling in lymph node matches as well as weight loss, in the last month i have lost 10 pounds without dieting. Thank you
