Hello everyone. so a short introduction. had PLIF to L3 L4 about 12 months ago. This was to treat chronic pain in my back and pins and needles to my thighs. About six months after surgery the symptoms came back. The thing is is that its not their all the time. If i'm pottering about the house its not much problem. However, if i go for a very short walk, ie around a shop it begins. The pain is so intense that i have to sit. Severe numbness occurs to my thighs with sharp stabbing pains and pins and needles. After sitting for about 20 minutes i can again walk a short while before the same senario starts again. My consutant says the my mri reveals no problems and further surgery is not called for. My doctor wants to prescibe me oxycontin, but this med will have me spaced out most of the time. I have been refered to the pain clinic and i think i will wait to see them before trying any narcotics. Is this normal for people after surgery to have this form of come and go back pain? Thanks in advance for any thoughts or ideas.
