Do you have chest pain, whether there is swelling, blunt pain or sharp pain in the pain area, specifically in the first few costal cartilage. Is there any tenderness, whether the pain will radiate, whether the pain is deepened after deep breathing, coughing, activity, chest and fatigue. How long has the pain lasted? CT can detect the lesions and show the cartilage swelling and ossification. I suggest you do a CT check as soon as possible.
