Had ESI 3 weeks ago. Have not had one in years. This one worked really good and right away. I have been able to walk and stand for much longer periods of time. The pain sitting down has been increasing since the 2nd week. Pain is worse now sitting down and it's been 3 weeks. I see my PM next Friday. I am thinking about having another ESI in January. Has anyone else got a second ESI and did it help? Thanks.
