Rib pain on both sides of an 80-year-old man may be related to trauma, intercostal neuralgia, osteoporosis, costochondritis and other causes. 1. Trauma: If you suffer from trauma, such as impact injury, there may be rib fracture or local soft tissue injury, which is manifested as rib pain, and most of them can be seen as skin breakage or bruise. 2. Intercostal neuralgia: If you suffer from intercostal neuritis, due to the inflammatory factor stimulating the intercostal nerve, you may have rib pain on both sides. 3. Osteoporosis: Calcium loss in the rib bones may affect the absorption of nutrients by the intercostal muscles and cause pain in the rib area. 4. Costochondritis: Mostly caused by non-infectious factors, it can be manifested as pain in both ribs, and redness, swelling, heat and pain in localized skin can also be caused by infectious factors. The pain may radiate to the back of the shoulder, armpit, neck and chest, and may be aggravated by deep breathing, activity or exertion. It is recommended that people with bilateral rib pain go to a regular hospital in time, to clarify the cause of the disease, under the guidance of the doctor for standardized treatment, so as not to delay the condition.
