Who diagnoses cording?

Here I am again. I arranged a review at hospital. Infection is some of the problem so antibiotic program keeping me busy every 6 hours. Some of the issues on left are aggravation of existing shoulder and cervical nerve problems prior to surgery. Bicep and tricep muscles very sore and bursitis in shoulder. Exercises I was doing are now reduced for left and I'm off to hospital physio dept next week. I'm glad I brought the review date forward. I can see that some of you have been very brave with coping with cording and treatments for cording. It seems why cording happens remains a mystery. Won't it be a grand day when/if the reason is known and prevention strategy in place? I have slight cording on right. Now unsure if have any cording on left given the other issues there. Focused now on left rehab instead of those issues at present.
