When swollen lymph nodes are examinated it's important to check the size ant the consistancy.
Different medical conditions are associated with different types of swollen lymph nodes.
Most of the lymph nodes are considered normal if they aren't bigger than 1 cm, although, some doctors accept the range 1-2 cm as normal depending on the place where are the nodes located.

Do you already have swollen lymph nodes or you just wanna know how to detect them when examine yourself routinely?

No, I don't think I have any swollen lymph nodes. However, I have these knots in my muscles near the areas where there should be lymph nodes. Like on the back of my neck muscle there's a sore knot, and on my shoulder muscle there's a sore knot.

They bump up a bit, but they're not really pea shaped and they don't move around.

Lymph nodes aren't embedded within muscles are they?
I've never had any lymph nodes swollen on my before, other than the one under my jaws/chin area for when I had a sore throat. I don't know how to tell how they look/feel and where exactly they are. I just know generally, and that is just a bit confusing for me.
