The reason I went to my doctor was because I was so tired that I was having a hard time functioning. She felt the lump in my neck during her exam. I had thought it was just a swollen lymph node. CT scan and ultrasound showed the tumor. In looking back, for over a year, when I rolled over to my left side in bed I had a strong nauseous feeling that went away when I rolled back. Also I was in the ER a few months before diagnosis because I felt like I was having a heart attack. I now think I ate or drank something that restricted my airway. Combined with the restriction the tumor was also doing, it made it more difficult to breathe which caused me to panic.
