Trashed my shoulder about a year and a half ago while mountain biking. Had surgery on it in October to repair a slightly torn rotator and calcific bursitis...
I thought it was repaired. I got back to my life as before... back to bike riding, etc.
Then I spent a weekend offroading and my shoulder started acting up again. It became inflamed and swollen. The latest MRI showed a severely torn tendon and a torn ligament also. I honestly have trouble identifying the traumatic event that could have torn up my shoulder again, but it is what it is.
Hopefully it's repaired. This last surgery was far more intrusive than the first. It's going to take me months to get through therapy.
