HEllo forum folks I am very frustrated with whats going on and i hope that i can recieve help from some of the people that has knowledge. I hurt my back at work and had sciatica twitching went to the emergency room and was diagnosed with an annular disc tear at the L-5, S-1 area. It has been two years since then and the insurance company ordered another MRI and now a doctor says that he doesnt see an annular tear at the L-5 S-1 area. My question is that is there a chance that the MRI didnt get the the vision of the tear. My legs go numb and i was hoping to have surgery and now the Dr. says he doesnt see anything and i was lying down on the MRI. I dont understand .. Do annular tears heal on their own. If there wasnt anything wrong with the disc then why is my legs still numb and twitching with sciatica.
