A little over a year ago, I discovered three small lumps in my neck. I started to get anxious about them, so I decided to go to the doctors. He said that I had a few slightly enlarged posterior cervical lymph nodes and they were probably due to a recent cold or virus. A few months later they were still around the same size so I went back. He told me they were around 1cm (though they felt larger to me) and that I should keep an eye on them to see if they get larger, and that sometimes they can become permanently enlarged. Well, it's been over a year and as far as I can tell, they haven't gotten any larger, but I can still easily feel them.
The thing that bothers me is that I read about this particular lymph node group, and almost every site I look at says that if the Posterior Lymph Nodes become enlarged, it is commonly due to malignancies, leukemia, or lymphoma.
I am a 25 year old male. I've had no fever, night sweats, or any other symptom besides the lymph nodes. I've had blood work done on two separate occasions, which have both been fine. I've also had a monospot, HIV test, and TB test, also OK.
I've just had a bit of anxiety lately, and have grown a little concerned over this.
Any advice would be helpful.
Thanks!
