Unfortunatelly Many Physiotherapists dont have experience treating cording. There is not much research about the best way how to treat cording; however, at the moment there are two treatments 1st breaking manually the cording by an expert therapist and secondly stretches exercises on the wall. I review my patients after they develop cording about 2 or 3 times. It resolves with exercises in few weeks. It is not a nice feelin, the tightness and the pain going to the arm or even going down to the abdomen and leg but don't get scare kep moving and stretching your arm.
Best wishes to any one who develops cording Cheers
