For myself I relied and still do on my faith to heal and make progress. It sounds like you are in good hands & will know more after the injection. If you’re having an epidural it will determine what discs are compromised. The surgery has a very high success rate. I was on an anti inflammatory diet and was as physically active as possible prior to surgery. Following nerve decompression the nerves rebuild and heal. Sending you healing thoughts & keep us posted on your progress
