Pain in the lower abdomen can have many causes, including: Constipation (very common) Gas or indigestion A stomach or intestinal infection Urinary tract problems Muscle strain Conditions such as appendicitis (often starts near the navel and later moves to the lower right side) Staying indoors is more likely to contribute to constipation if you're not moving around much, but it is unlikely to be the sole cause. A few questions: How old are you? How long have you had the pain? Is it on the right side, left side, or middle of the lower abdomen? Do you have constipation, diarrhea, fever, nausea, or pain when urinating? These details can help narrow down the possible causes.
