I recently had a full diskectomy at the L5-S1 level. The herniation at this level was massive causing severe canal stenosis. The herniation was on the right side, irriatating the S1 nerve root. The pain you have described that extends down your calves , under your ankle and out to your little toe is consistent with S1 nerve root canal stenosis. However, the severeity of your pain is not directly proportionate to how herniated the disc is. In other words, the degree of pain has no direct corrolation to canal stenosis. Some people experience severe pain with a protrusion.DEFINITELY GET A SECOND OPINION. If you do not feel comfortable with your neurologists findings or his bedside manner, you need to get a general concensus from more than one doctor. In some cases you may be dealing with a very big personality. So big that it may be effecting your care. A radiologist is low on the "totem pole" compared to a neurologist. That being said, most radiologists spend very little time reviewing your images. In most cases it is dictated in a few minutes or so. In addition, tingling and numbness are symptoms but pale in comparison to what you could or may feel in the future. I don't think that you are at "red alert" status or even should consider surgery at this point. Take it from me, you do not want to start removing parts of the infrastructure of your back. It leads to possibly having more complications and even more surgeries that are much more invasive. As in my case, I will be having a spinal fusion in the near future. My advice would be to seek alternatives and only consider surgery as a last resort. Avoid it if you can. That may be disconcerting to you as you are in discomfort and seek relief but your only at the start of a long frustrating process that will undoubtably change your life as you know it. Have you tried injections, steroids, acupuncture, pool therapy, a chiropractor or other avenues? These should all be entertained as possibilities rather than hoping for a "quick fix" to your discomfort. Avoid surgery if you can....please. I may sound similar to your neurologist and seem to downplay your situation. It can get much much much much worse. Hopefully I have been some help. I wish you the best of luck as you will need it.
I too am thinking that is going to be my next request after I get a discogram done next week. The Neurosurgeon had me do an EMG to test my nerves and then a discogram where they inject dye into my disc and see if it leaks out. But I am thinking I need a Microdisectomy as the other two Neurosurgeons recomended.
I'd get a another opinion if I were you....Good Luck!
