If you are experiencing sudden pain on the right side of your ribs that only lasts a few seconds, it is possible that it could be related to a rib injury or intercostal muscle strain. In most cases, this type of pain should decrease over time as long as you are not coughing frequently. However, if the pain persists or worsens, it is advisable to consult a doctor for a physical examination to determine the exact cause of the pain and initiate appropriate treatment.
