I had a spinal fusion back surgery done last year in March of 2012. I recently have been getting injections to the thoracic spine. I just recently had one on Friday and today is Sunday and I am experiencing some extreme difficulties. I am in severe pain and my legs are completely numb. I only walked maybe maybe 2 feet to my bathroom and now I can not walk. Any time I try to stand up I end up falling right down.I also have been having severe pain in my lumbar spine area as well. I am unsure of what I should do at this point. The pain is just unbearable. I have also been having short lasting fevers. If any one could please give me any advice as to what I should do that would be wonderful.
