My daughter is 10 months old. She woke up crying two days ago. It wasnt her usual cries. It sounded like she was in pain. When i lifted her up she held onto me tight crying in pain everytime i touched her butt area. I thought she was constipated. Then today, as i was changing her diaper, i noticed that she was hurting when i hit a specific area on her buttocks. Like around her tailbone. Her diaper also contained some blood.When I had changed her diapers the last two times, it looked like a little spot of poop. I thought she was finally pooping alittle. But the third diaper I changed today had blood. I felt and examined her butt and I felt this big, hard, reddish, pusey, bump around her crack area. I'm worried. Should I be concerned?? Is this "Pilonidal Cyst?" She's only 10 months old...how did she get this??? What should I do?
