What could be causing my swollen lymph nodes?

[MadiBogden]

Hello! My name is Madison, and I need to figure out why my lymph nodes are swollen. I'm 17 years old and 120 lbs. (5'6) I am a severe asthmatic. (That is the only health issue recorded) So I have quite a few lymph nodes that are swollen and hard. I first noticed my "first" lymph node on my neck. It was by where my jaw connects to my neck and its sort of hard to feel. It's about the size of a nickel, and quite hard. That lymph node has been present for months now. A couple months ago I noticed another lymph node right beside it with the same hardness, and just a tad smaller. I then noticed some squishy, dime sized lymph nodes in my pelvic area. I then noticed another hard, dime sized lymph node on the opposite side of my neck, and one I believe on the side of my breast. I now just noticed yesterday that I have a quarter size (estimate) lymph node directly in front of my left ear. It's hard, and moves a little. Here's some more information: I get sick quite easily, Just in the past 2 moths I've had 3 ear infections that required two types of antibiotics and a couple chest infections (pneumonia & bronchitis). My infections seem to be long lasting & and more severe. (My ear infection went from a simple swimmers ear to almost infecting my mastoid bone in just a couple of days) I've also had tests done for the lymph nodes. I had a CBC, which came back normal. Also, a thyroid function tests and a mono spot test which all came back that those weren't the problems. My doctors just gave up on it I guess and Id like to know what could be causing my swollen lymph nodes! And I thought this would be the right place.
