Individuals should seek immediate help if they experience right rib side pain accompanied by trouble breathing, according to Healthline. They should also seek immediate help if they experience pain while breathing, pain when moving into a certain position, pain after a fall or intense bruising.
Patients experiencing side rib pain with any breathing issues should immediately seek medical help because these symptoms may indicate a heart attack, according to Healthline. Patients with substantial rib bruising should also seek medical help because it may indicate a rib fracture.
The most common cause of side rib pain is generally a pulled muscle or bruised rib, reports Healthline. However, side rib pain may also result from osteoporosis, muscles spasms, inflamed rib cartilage or inflamed lung lining.
