I have discovered a lump in my neck sort of mid way down in side, about 3 inches below jaw line. It feels small (1cm or smaller) and hard like bone. It hurts if I push hard on it. I can feel one on other side as well but not as easily. Of course with health anxiety I'm jumping to conclusion of lymph nodes, but wondered if it could be cartilage or bone there. If they are lymph nodes it's a worry as they are very hard. Can anyone else feel similar thing? I do have very tight muscles in my back and neck but don't think it feels like muscle as sort of round and feels too hard to be muscle. Thought could be part of thyroid cartilage but I think thyroid is more in middle, this is further to the side. I could ask doctor but feel a bit stupid as I was only there last week thinking o had breast lump which turned out to be nothing.
