Around almost 3 weeks ago my left ear piercing had became infected and was bleeding and oozing and I soon noticed that the left lymph node had became swollen and I had a sore throat at the time but the piercing has now started to heal and haven't really been bothered by it again until now and I can feel the lymph node still abit hard but only when I really feel for it and it also makes a clicking sound and pops a little when I touch it , and it hasn't really caused me pain since until now when I've been feeling for it. I have extreme anxiety over my health too and I can't figure out if I'm just thinking it about how it feels and I can't tell whether it feels normal or not. I can only feel it when I turn my head and it seems quite hard but it is also hard but not as much the other side but I can't tell if that's my jaw bone.
