Its normal. ESPECIALLY if you have been poking and prodding, like it sounds like you have. You probably had one typical node, touched your neck and made a bunch more swell up.
Also, different nodes in different parts of the body do have different sizes+ shapes an feelings. The one under your jaw is the same as me, mine is a bit bigger there as well. And is especially sore and I can feel it sometimes in certain positions. Sometimes my neck feels full. But it has been the same size and is extremely mobile, soft and sore.
Chelseafan, I remember you writing about leukemia on here before too. ANd you did not have have. Try to remember that this is the same thing again. I know how you feel..we think of leukemia for example and then our fears are dismissed than we run onto another disease that has even one similar symptom and say OMG THAT IS WHAT IT IS.
I don't think you have lymphoma. And I should take my own advice cuz my symptoms are the same as yours and I have had many doctors see me and say I am okay + bloodwork is clear. I hope that helps.
