For About 6 months, I have had small lumps under my chin (less than 1cm). These were at first large as I had tonsillitis, but after antibiotics, they got smaller and stayed that way. However, 2 weeks ago, I went through a simple sore throat and noticed 2 irregular lumps on both sides of the jaw, and both underneath it, on about 4cm in size and the other about 2 cm in size. I decided to monitor these, and they have been getting smaller (after 2 weeks, the smaller one is approximately 1 cm in diameter, and the other about 2) They are both still irregularly shaped and hard, but moveable. The problem is that I am a hypochondriac, and and I have been squeezing the nodes in all palpable areas very hard, and new lumps have been popping up. These seem to enlarge up to about 1cm overnight and then stay that way. They have only done so in the groin however, but new ones apppear all the time. All the other areas of the head, neck and under the armpits are clear. The nodes in my groin are smooth but painful, but not to touch I have been cycling a lot and my legs have been sore, could this cause such enlargement?. The lumps under my jaw are painless. I am only 15. I am suffering no other symptoms. So, I have a couple of questions: Can this be lymphoma? None of the lumps are getting larger. And is it physically possible for an infection or malignancy to spread from under the jaw to the groin without affecting the lymph nodes in the clavicle and neck?
