At the age of 27 with two years of back and leg symptoms having failed epidural injections and a documented herniated disc compressing the nerve, I can’t understand why you have not been referred to a spine surgeon.
Personally, I think that patients that receive relief from epidural injections can continue to get them every four months. The fact that a needle could not be placed in the “proper place” is a reflection of the injectionist and not of the pathology.
I however am not endorsing continuing injections. If a herniated disc continues to cause pain and the patient does not gain more permanent relief over a period of 3-4 months, they deserve a consult with a spine surgeon.
