Thank you for your query on Healthcare Magic.
Vomitings and pain in right lower side of abdomen are alarming symptoms.
Physical examination by a doctor is important to rule out acute appendicitis
which requires early intervention to prevent complications of perforation and peritonitis
which are dangerous complications.
abdomen and pelvis is needed to look for the condition of appendix
I advise you to take her to ER for physical examination with ultrasound abdomen and pelvis to look for this problem.
Hope I have answered your query.
