Has anyone had cortisone injections? My Dr. suggested injestions today (one each side, both shoulders and lower back, lumbar region) he said they have helped lots of people but only last 3 weeks. He said it relaxes the muscles of the upper shoulder/back and lumbar region, thus relieving the pain (shoulders, arm, neck and back and leg)that goes with these muscles being tense and inflamed. Has anyone done this??? Has it helped? I passed today, but wondered how it worked for you all. Thanks!
