I'm 21 years old. Two days ago I got a really bad cold and my throat hurt etc. I did notice the day before that on my right side of my neck in between my ear and shoulder that I had a pea size lump. I cannot notice it by just looking at my neck but if I tilt my head to the left and feel around I can feel it. Idk if I had this before or if it just came up since I got sick. Idk if it's anything to worry about or not. I've also been stressed a lot recently and I know that lymph nodes can swell because of that as well. I've been stressing a lot about my health recently and I think that's causing all my problems.
