Lower right abdominal pain without a fever can still be serious, since appendicitis, ovarian torsion, ectopic pregnancy, kidney stones, and hernias often begin before any temperature rise. Warning signs that point toward emergency care include pain that steadily worsens or migrates from the navel to the lower right side, a rigid or tender abdomen, persistent vomiting, blood in stool or urine, fainting, or pain during pregnancy. Milder causes such as gas, constipation, muscle strain, or menstrual cramps may improve at home, but timing, pain quality, and your risk factors all change the answer. There are several important factors to consider before deciding between the ER, urgent care, or watchful waiting, and they are explained below.
If you are unsure how urgent your pain is, a free, instant, online symptom check can help you sort possible causes in minutes, flag red flags that warrant immediate attention, and give you clear next steps and questions to bring to a clinician, so you neither wait too long nor spend hours in a waiting room unnecessarily.
