causes of soreness in chest
Hacking cough is the primary cause of soreness in the chest muscles. Persistent coughing puts a lot of strain on the chest muscles, chest wall, which eventually results in soreness. Sore chest muscles from coughing is mainly found in people suffering from respiratory disorders such as pneumonia, bronchitis, etc.
Often, chest pain can occur due to sore chest muscles. Soreness in chest muscles is often due to repetitive, excessive use of muscles, or due to trauma to the chest. When strong force is applied to the chest region, beyond what the chest muscles can bear, the muscles of the chest get bruised and injured.
