[|Human|] Sunday I had a bump appear on my neck, not huge but noticable. Well it is now Wednesday and it is about the size of a dime and a small bump has just appeared above it. It doesn t hurt unless I mess with it and it isn t red or discolored. What could it be? I haven t been sick, beside the bumps I have only been fighting headaches.
[|AI|]  Hello! Thank you for the query. Bump on the neck can be a lymph node (enlarged), sebaceous cyst or any other benign soft tissues lesion (like lipoma). As I am unable to see it and examine it, It's really hard to give precise diagnosis. Enlarged lymph node can appear due to some kind of infection (which you may not even notice) including teeth infection, ear infection. Lymph node is usually hard, rounded and movable. In most cases lymph node does not hurt, however when pressing it or touching, can become painful. Sebaceus cyst is a benign soft tissues lump, filled with whitish masses. It does not turn into a cancer. However, it may become infected (if so it starts hurting). The best you can do with this lump, is to have soft tissues' ultrasound done. Hope this will help. Regards.
