I had two lumbar puntures in 1986 and have have back problems ever since. During my procedure i lost feeling in my leftr leg and had to have the procedure repeated by another person. with better results. After words when i sat up i began to vomit and was assisted home. i had a 1 1/2 years of physical therapy forr my lower back and given a back brace to wear. I loose control of my bowles, lots of lower back pain when i am in astanding position for more tham 5 minutes, shooting pains down my leg. Couuld this procedure have caused a bulging disc on L5/S1 which is what was found on my MRI.
