I Have 3 Swollen Lymph Nodes On My Neck 1 Under Arm & 1 In Groin, What Does This Mean?

Hey,
I have the same problem. I went to the doctor and he said that everything is perfect.
I am still paranoid because I keep thinking I have lymphoma. Anyways, If you find out
anything, can you please tell me?
& I pray to god that everything turns out alright for you.
