I want to know the side effects of cortisone injection

Cortisone may be anti-inflammatory and may be a quick fix for pain but it is not healing of tissue damage. There is a risk of slowing any healing, particularly if there are repeated shots. Physical therapy before, after, or in substitution for the shots may be the better call in the long run. But if you are in so much pain you can't sleep, it clearly makes sense to get some pain relief.

So, how will you be? That depends on the nature of the injury, the cause of the injury, whether or not you participated in physical therapy, and whether any healing took place or any other corrective measure was taken. Sometimes, the problem resolves itself. A slower route of physical therapy may yield benefits which last longer than a route of repeated shots. Some evidence suggests repeated cortisone shots increase the chances of relapse within 6 months. That said, the devil is usually in the detail and any general advice may not apply to your specific situation. You might check the Mayo clinic website for some background information but your physician knows more about your particulars.
