Hello, It can be signs of appendicitis. You consult a surgeon and get evaluated. The classic symptoms of appendicitis include: 1. Dull pain near the navel or the upper or lower abdomen that becomes sharp as it moves to the lower right abdomen; this is usually the first sign, but it occurs in less than half of appendicitis cases. 2. Loss of appetite 3. Nausea or vomiting soon after abdominal pain begins. Other causes: 1. Gas Intestinal gas is air found in your entire digestive tract. It’s often caused by food that’s not broken down completely until it reaches your colon. The more undigested food present, the more gas your body will produce. As gas builds up, it can cause abdominal pain, bloating, and a “knotted” feeling in your stomach. 2. Indigestion Indigestion (dyspepsia) typically develops after you eat or drink something. Pain usually occurs in the upper abdomen, though it may still be felt lower down. 3. Kidney infection A kidney infection is caused by bacteria that usually come from your bladder, ureters, or urethra. One or both of your kidneys could be affected by the infection. Although you may feel pain in your lower abdomen, discomfort from a kidney infection more often occurs in your back, sides, or groin. Hope I have answered your query.
