Evie -
After surgery, you will most likely have funny sensations due to your nerves having been 'disturbed,' for lack of a better word. They've been jostled, and only now have been freed from any compression, so your nerves are sending some crazy signals out.
I had a laminectomy Dec. 05 and had a burning spot on my thigh for at least 3 months after surgery. It finally settled down, so you should hope for the best.
Also, your surgeon/doctor can prescribe you something like Topomax (don't accept Neurontin as a substitute) that will help the nerves out a bit.
