This is the surgery i am getting done next month, by one of the spine clinics orthoepedic surgeons. Its minimally invasive and is supposed to have a good success rate, so im hoping for the best.

This site has many animations of different procedures and surgeries including Epidural injections, i thought some of you may want to check it out, especially those of you who are very new to it. You can get a detailed picture show with an easy to understand step by step explanation. It also has a slideshow on the anatomy of the spine. Hope this helps some of you :)
