Take it easy and rest your strained muscle. Most muscle pulls occur from either lifting too much weight, doing something too often (repetition), moving awkwardly or experiencing trauma (car accident, sports injury). The first step with any muscle strain (and most musculoskeletal injuries in general) is to rest it.
** If you have a chest muscle strain, or a chest muscle tear, you are now, by default, on the path to Tendonitis. A pulled chest muscle can be minor, or severy. Pulled chest muscle symptoms are NOT to be ignored. Listen to what your body is trying to tell you, and treat it right. The more you know what's going on, the better post-injury self care you give yourself, the faster your pulled chest muscle symptoms will go away.
