appendicitis is different, the pain originates in the abdomen and slowly migrates and centers at your appendix. which is lower right from your belly button. or upper right from your genitals.
I had a ruptured appendix last year, it was the most excruciating pain I have felt thus far. It was very painful for 1-2 hours, then it didn't hurt very much if I did not move around. The next morning when I decided to go to the doctor, it hurt just to get out of bed and to walk around. The doctor sent me to ER and within 12 hours, I had to do a appendectomy. All my symptoms were that of a ruptured appendix. I was hospitalized for 4 days in total so the doctors can keep me on antibiotics because my appendix had ruptured, which can cause infections in the intestines. Luckily this didn't happen to me.
1 month later, I have recovered from the surgery and everything, I went to a scheduled appointment with the surgeon, he told me the analysis of my appendix showed that it was a "chronic" issue that led to the rupture. I recall having 2 bad stomach aches months before, something like 3 months and 6 months before the date it ruptured. At those times, I didn't think much of it because it eventually stopped.
I hope you are not experiencing a precursor to appendicitis!
