I had a cyst on the side of my neck that I removed a few months back. A new cyst has grown in the same spot, but the opposite side of my neck, and now I m feeling another lump when the removed cyst was. The side the cyst was on for the first time hurt, and so does the lump on the exact same spot, if that helps. Can someone please explain what s going on, if I should be concerned, ect. I m 15 years old, average height and weight, and besides the cysts, perfectly healthy.
