I had a left shoulder injury while working working out at a gym around 5 years ago. Upon doing a MRI it was founded that the bursa had inflated giving pain as well as few tendons were damaged. I had gone through medicine's, multiple rehab sessions, physio sessions, mild workouts at home. However, my body says it's still not 💯 and I still feel the tingling sensational from time to time upon exercising it a bit. I am planning to get back to shape and workouts this year. What can be a permanent solution for this..? Cortisone Injection? Pls advise. Thanks.
