Twice my daughter has had severe bouts of abdomen pain focused in the lower right quadrant. One at age 8, and one at age 12. Each time, docs were intially certain of appendicitis
, but later reversed their opinion. The last time at age 12, every doc she saw and 2 ERs were convinced she had appendicitis...all physical symptoms were present as far as pain, rebound tenderness, location, inability to pull leg up to chest, etc.
