Costochondritis is inflammation of the areas where your upper ribs join with the cartilage that holds them to your breastbone. These areas are called costochondral junctions. The condition causes chest pain, but it’s typically harmless and usually goes away without any treatment. But any chest pain in adults should be taken seriously, so you should be examined and tested for heart disease. //

Chest pain linked to costochondritis usually comes on after exercise, minor trauma, or an upper respiratory infection.

Sharp pain in the front of your chest, near where your breastbone and ribs meet, typically on the left side. It may spread to your back or belly.
Pain when you take a deep breath or cough. It gets better when you stop moving or your breathing is quieter.
Tenderness when you press on your rib joints. If you don’t have this tenderness, you probably don’t have costochondritis.
If costochondritis happens because of an infection after surgery, you’ll have redness, swelling, or pus discharge at the site of the surgery. //

These home remedies may provide relief from costochondritis:

Over-the-counter pain relievers such as nonsteroidal anti-inflammatory medications (NSAIDs) like ibuprofen or naproxen as needed
Using local heat or ice to relieve pain
Avoiding unnecessary exercise or activities that make the symptoms worse; avoiding contact sports until there is improvement in symptoms, and then returning to normal activities only as tolerated
Doing stretching exercises //

Costochondritis Outlook
Noninfectious costochondritis will go away on its own, with or without anti-inflammatory treatment. Most people will recover fully.
