When it is the injection needed
If rest, medications, and physical therapy do not relieve your pain, an injection of a local anesthetic and a cortisone preparation may be helpful.
What it is
Cortisone is a very effective anti-inflammatory medicine.
How is it injected
The physician carefully inserts a needle into the joint space in the shoulder and injects the cortisone solution. The solution goes into the joint space to reduce pain and inflammation in the joint.
