Hi welcome to the health care magic Right Lower quadrant abdominal pain could be from appendicitis or from colitis... USG abdomen needed here for further work up Physical examination for eliciting tenderness if present ruled out CRP can be done here as initial work up You might prescribed antibiotic for these condition if needed If repeated appendicitis is the cause than appendix has to be removed If USG suggestive any growth like lesion than colonoscopy done Sometime even stone on lower ureter can be responsible So depending on cause specific treatment planned Consult physician for examination Take care
