Here is an update as years of healing has passed from a severe torn pectoral (Severe pectoral muscle belly) due to flat bench dumb bell presses. (March 2011)
As you can see in these pictures I will always carry an indentation of this horrible strain/tear. My pressing moves have diminished due to this , and over the years pressing dumb bells or bench press on flat benches are difficult and awkward. However I did gain back a lot of strength but still lacking about 20% of what I used to press. Incline presses I can still do much better and much more weight. On flat bench the muscle rolls to the middle of my chest and I defiantly feel a degree of weakness as my left side favors such. All my other weight routines have not been affected.
When this happened I went to a Sports Doctor because it is prudent to seek a treatment of this nature in the right field. I had an MRI done to confirm that it was not a tendon tear. As far as Muscle surgeries, there were none offered that would completely heal me back to normal. So here I am still struggling but accepting that this is a fact and I am still able to lift. I had researched and found that ART Active Release Therapy was my answer when this happened. But it was not. In fact it did nothing. It probably would if I had a tendon tear. However I learned too late that If I went immediately to a good message therapist, He or She could have over time worked the muscle scar tissue out and into workable muscle fibers bringing the muscle back together. This would have not been a complete healing process. So in other words skipping the time spent in ART and going to deep muscle massage therapy the outcome would have been better. I did do many sessions of deep muscle therapy in the tear area and it helped tremendously. However my therapist told me that if I had come in shortly after the tear they could have worked the muscle fibers closer to bind and mesh verses the scar tissue that had built up.
I hope that anyone who has a similar tear gets an MRI and determines the best route to recovery. And you consider therapy as soon as you can. In fact, let a muscle therapist determine when you should start sessions. It may be too soon on your injury to start. So please get a professional opinion.
Good luck and in healing.
