Pain or a weird feeling in the lower right side of your belly can happen for many reasons, such as muscle strain, an inflamed part of your digestive system, or even a less common issue like iliopsoas bursitis related to how you sleep.
Your lower right abdomen houses many important parts like muscles, intestines, and other organs. Sometimes a strange feeling there can be from a pulled muscle or a tight spot that happens when you sleep in an unusual position. For example, one study talked about how iliopsoas bursitis, which is swelling of a small fluid-filled sac near your hip, caused pain in that exact area. Other possibilities include issues like appendicitis, problems with the small or large intestine, or even a hernia. Though many of these conditions can be mild and temporary, some might need medical care, especially if the pain lasts, gets worse, or you develop other symptoms such as fever or vomiting. It’s important to remember that only a healthcare professional can give a proper examination and determine what is causing your discomfort. If you are worried or if your pain does not go away, please see a doctor to have a careful check-up.
