Pain in the lower right side of the abdomen, along with a report of subacute appendicitis, usually means the appendix is inflamed but not yet severely infected or ruptured. Some people feel better for a while with antibiotics, rest, and changes in diet, but others may have pain that comes back after a short break. Whether to use medicine or surgery depends on how bad the inflammation is, if there is fever or vomiting, what blood tests show, and if any complications are starting. Doctors may try medicine first if the case is mild or caught early, but appendicitis can become dangerous if the appendix bursts and infection spreads in the abdomen. Because of this risk, surgery is often the more reliable and lasting treatment, especially if pain keeps coming back or scans show the inflammation is getting worse. Eating heavy or oily foods and taking painkillers on your own can sometimes hide symptoms and delay proper treatment. If the pain suddenly gets much worse, fever goes up, vomiting increases, the abdomen feels hard, or it becomes hard to walk, get medical help right away, as urgent surgery may be needed for complicated appendicitis.
