Hi, Thanks for writing in. Ossicifation of costal cartilages is the conversion of cartilages in the front portion of ribs into bone with deposition of calcium and this is normal at any age. You have probably age related degenerative changes in the upper part of chest where the ribs meet the breast bone on the right side. This may be causing pain and discomfort. Little amount of fluid is also present in the region. Initial treatment of the pain and functional disability associated with costosternal syndrome should include a combination of the nonsteroidal anti-inflammatory drugs or the cyclooxygenase-2 inhibitors. The local application of heat and cold may also be beneficial. For patients who do not respond to these treatment modalities, the following injection technique with local anesthetic and steroid may be a reasonable next step.
