Pimple-like Bumps On Neck Near Lymph Nodes

For the past year every time I'm nearing a cold or have a cold or even just an allergy, I get these pimple-like bumps literally on or around my neck lymph nodes and they will stay for quite some time.  Usually during this time my lymph nodes are also swollen, but I don't necessarily have a sore throat.  I'm wondering if this is something I need to be concerned about.  Once about 6 months ago, I went to a MD regarding H. Pylori I had which triggered swollen glands, and asked about the sores then, but the MD had no clue and told me it might just be pimples.  I heeded the advice, but since then it has happened four times!
