Over the years I was injected cortisone shots in my shoulder, and knees. The doctors srayed a very cold substances and then injected. It did not last but had no side effects.  3 days back I went to another surgeon who gave me the cortisone without  cnumbing the nerves in my shoulder. After about 25 minutes, I started getting head ache and that intensified and ever since I have head ache and my stomach is upset. I always have chronic constipation but now I have bloating sensation, and have diarrhea not that much. Feel feverish and still with head ache. What's going on? help me. Thanks
