Muscles or tendons in your chest have been damaged. Tendons are made up of very firm connective tissue. Tendons attach muscles to bones. The symptoms depend on which part of the chest has been injured. It may be, for example, that breathing is more difficult than usual. You may also find it more difficult to move your upper body or arms. You may also have pain.
