2.5 months ago I felt a soft, spongy lump near my jaw (right side. And it hurts a little. I noticed I had cold that time. Gradually that lump becomes softer and smaller. Again after 3 days. I felt a lump on the other side (left. This time I had cold too. Actually I have cold allergies. The fact is that till now both the lumps doesn't hurt but they didn't gone away. They are still there in same size. Recently I noticed a small-lump in my underarms (it is not visible but I can feel it. I am very tensed if it is lymphoma or anything serious? I have no other symptoms though. My weight is 77 kg. And I am 18 years old. Can you suggest what should be done?
