I am 29 years old woman and got a painless, soft lump on the right downside of my neck. When I press it, it goes in. I went to the doctor but she said it is okay, just got swallowed from infections. I got this lump like two years ago and now it looks like there two one smaller above the first one. I am not quite sure if it is lump or more like bump. Is it something I should be worried about?
