I'm wondering if I'm at the beginning stages of paralysis? I have Spina Bifida but have been able to walk since birth. However, in the last three months stiffness in the legs has increased, pins and needles in my feet and legs, no strength in my lower back, no strength in my legs when I walk for long periods of time, it feels as if the muscles in my lower back and legs are shutting down. Kind of like my brain is saying walk but the muscles are saying "We can't" we don't know how anymore???

Anyone ever been or seen someone able to walk and then lose their ability to walk? Specifically from something non-tramatic or accident related?
