Costiochondritis not getting recovered.

I was diagnosed with Costiochondritis in Mar, 2024 by an Ortho specialist. He took an X-ray, ct scan also later in the treatment process. Talking about the treatment, we did try NSAIDs, hot pack and cold pack, chest binder, ultrasonic physio therapy, calcium tablets. At last he suggested a steroid injection at the injured location. I read about the steroid injection that it will only cure the inflammation and not the underlying injury. This was one reason i did not go for steroid treatment and another was that i was tired and depressed about this disease now. because they say a normal patient recovers from it  ranging from a few weeks to 2-3 months. But this disease has been with me for almost 9months now.
