does anyone have any new suggestions of how to treat FBSS without controlled substances and or surgical intervention. All have failed along with traditional therapies over the course of 6 years. The patient has epidural fibrosis around the nerve root and is regressing in pain and activity. Nerve conduction study and new MRI will happen in the next two weeks. Is pentoxifylline and vitamin e been proven to help this case of epidural fibrosis? I have read one article that has supporting facts but wanted to know if there is anymore recently published articles about this.
