My neck had been bothering me for the past 2 or 3 days and was a little stiff on the right side only, i thought this was due to the fact that i play tennis and am right handed (or i just use my right side a lot more in general) and that my right side was just stiffer because i never stretched and stuff. However i was poking around and right where the front right of my neck connects with my collarbone, there seems to be a small lump that feels a little firmer and jiggly. Around 3 days ago i felt a little bump the right side of my windpipe that is a little painful if pushed. My neck also feels a little stiff.
I was just wondering what a lymph node in the collarbone should feel or look like to be considered enlarged and/or a sign of cancer. Please help me i'm really freaking out.
