Difficult to assess: based on the information given. I would see your doctor for a detailed history and examination soon. The differential diagnosis list is vast, and many conditions should be ruled out. If your symptoms progressively worsen or you develop a fever, go to the ER immediately as this could be a presentation of appendicitis. For now, monitor and schedule your appointment. All the best.

Umbilicus: Hernia of the umbilical area is a possibility, but the symptoms could simply be due to abdominal muscle strain. If symptoms persist, have your physician examine the umbilicus,and abdominal wall.
