The benefits from the first shot only lasted 2 weeks. The second and third set of injections lasted about 90 days. In November, I was ready to have surgery. My EMG and nerve conduction tests proved that the nerves were "sleeping" before I was. After another MRI, the neurosurgeon said I was a candidate for surgery but I was not able to get the endoscopic type surgery that is less invasive. I would have an incision about 6-8" long. Along with removing the herniation, they would have to increase the size of the hole where the nerve roots were going through.
Lumbar Puncture . Lumbar puncture is useful for identifying infection, the presence of red blood cells (which suggests bleeding), and abnormal cells associated with some CNS malignancies. In adults with suspected subarachnoid hemorrhage, it is important to perform lumbar puncture to check for blood or xanthochromia. Computed tomography of the head should be performed before lumbar puncture, even if the results of neurologic examination are normal, because there is a risk of central herniation of the brain even in the absence of physical examination findings of subarachnoid hemorrhage. In one supporting study, 5 percent of patients presenting to an emergency department with suspected subarachnoid hemorrhage and a normal neurologic examination had early intracranial herniation or midline shift. 29
