The symptoms and treatment of chondromalacia include the following. The symptoms of chondromalacia are mainly pain because it is a sterile inflammation, and this inflammation will exude some inflammatory factors, including prostaglandins and interleukins, which will cause local pain, usually sharp pain or fire-like or knife-like pain. Of course, local swelling may also occur, as the inflammation will exude and cause local soft tissue edema. Other symptoms of nerve damage may also occur because the intercostal nerves are relatively close together, and at this time, costochondritis may irritate the nerves causing radiating pain. The treatment includes the following: 1. give some non-steroidal anti-inflammatory and analgesic drugs. 2. give oral drugs that activate blood stasis, improve circulation, and strengthen the muscles and bones. 3. apply topical creams locally. 4. perform physiotherapy locally.
