Is there a cure for costochondritis?

I do not think so: The goals of treatment are to reduce inflammation and to control pain. To accomplish these goals, nonsteroidal anti-inflammatory agents (nsaids) are used, with Ibuprofen usually selected as the drug of choice. Additional treatment, moist heat, and steroid injection.Thank you.

Usually: True costochondritis will sometimes resolve with conservative management but on occasion an injection of simple Lidocaine will do the trick.

Yes: Usually it will calm down with a decent nsaid medication. You may need to refrain from heavy exercises especially using your upper extremities. It can sometimes take several weeks to calm down, but usually is not a chronic problem.
