What are swollen lymph nodes like?

Lymph nodes are the junctions in your lymph system. They are widely distributed throughout your body but are most prominent in your neck, in your armpits and near your groin (in the fold between the top of your leg and your body).
You can sometimes feels them as small bumps about the size of a pea. If they are swollen they are slightly larger, harder, and easier to feel.
They swell because this is where most of your CD4 immune cells rest. When you body has an infection, the immune cells nearest the site of the infection increase, and this increases the side of the lymph nodes.
If you cut your finger and get an infection, the lymph nodes for that arm will increase. If you get a sexually transmitted infection, the lymph nodes in your groin will increase.
