Welcome to the MedHelp forum!
Lower right abdomen pain is commonly due to appendicitis but this has been removed, so ruled out. Crohn’s disease, diverticulitis, infection in kidney, kidney stones, constipation, ovary involvement in women (PCOS), ectopic pregnancy in women, mesentry (a thin tissue that carries the blood, nerves and lymphatics for the intestine) involvement, and an abscess in rectus abdominis muscle or psoas muscle can all cause lower right abdomen pain. Since you had a kidney stone earlier, this should be looked into. Also it can be due to Crohn’s disease or IBS if you have other gut issues like gas, diarrhea or constipation. Possibility of ectopic may not be there in your case, but should be ruled out if you miss your periods.
I am sorry but it is difficult to pinpoint a diagnosis on net. If possible get urine examination done to rule out infection, blood in urine. Also try and consult a doctor.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
