What S Causing Lumps Near The Collar Bone, Fatigue, Daily Headache And Painful Jaws/ears?

Hi my name is cristen and this is my first time using this so i may not be doing it right. About 6-8 months ago i had to big lumps in my throat above my collar bone. One of them has almost completely gone away but the other one on my right side is still there. About 4-6 months ago was when i realized that i had a smaller one right beside it. Its not as hard as a rock and it don t hurt unless i push on it hard or try to see if it moves. Now about 2 weeks ago i discovered ANOTHER smaller lump on the side of the second lump. So now i have a lump as round as a a half dollar,another lump that seems more plump that is the size of a quarter,and now a smaller one thats about as round as a nickel. I have been getting more and more tired lately and getting headaches everyday.i have bad teeth in the back of my mouth but they have never gave me problems with my jaw,ears and head aching but now im going through all of that. What are the possibilities so i at least know what i can expect when i can afford to see a doctor
