Left Legs Issues

I had a pseudo-tumor in December due to a buildup in brain flu.The pseudo was only discovered after an entire week of blurry and double vision and a visit to the North Shore LIJ Hospital. In order to correct it, I had to have a lumbar puncture. The doctors tried an unguided tour that yielded no results, but however, when the needle was inserted into my back, I felt a tingling feeling around my pelvic area. The doctors gave up and advised my mother to pursue an x-ray guided procedure. I had the procedure done and I stopped having headaches, double and blurry vision, but my legs give out after walking distances that I was accustomed to walking before my procedure. Is there any way that the unguided lumbar puncture could have severed the nerves that control my legs movement? If so, can I become paralyzed. Please help me, I am 17 years old and I don't want to become paralyzed.
