Before bed last night, my daughter came in crying- she showed me a small, marble sized mass of some sort in her pelvic area, over to the left. It literally feels like a marble is beneath her skin. This morning, it still hurts to the touch. I called the dr. at 8am, but her appt. isnt until 10:50. Have any of you had any dealings with this? I am so very worried- she is 8 yrs old and has was diagnosed on 10/15/08.
