Hi my name is Brenda B and I am scheduled to have an epidural injection on next week. I sustained an injury t my left knee in 2006 and have never gotten a definitve diagnosis, I have been told I have sciatica but it has never been confirmed by x-ray, MRI or Nerve conduction tests. Over this span of time due to limping and the use of a cane(I think), I also now have lower back pain. I am so afraid of having an epidural injection but I need something done for this pain both in my back and my knee and leg. I have had cortisone(no relief at all) and steroid injections in my knee and in my lower back in my upper buttocks area with only minimum relief. The Dr. has me scheduled for epidural injections Feb.8 & 29th & March 17th. Has anyone had these injections and can tell me that there is nothing to fear?
