I have a swollen, painless lymph node on the side of my arm. It is about an inch or so in size. It has been there for close to 3 months. Should I be concerned? i also have one under my armpit that is sore to the touch and has been there a couple of months. Please help me! I am uninsured and unemployed and if a doctor visit isn't needed, I would like to know to save the money. Thanks. PS. I am a male, didn't know where else to go.
