Hello, For years I have suffered from numbness in my thigh intermittently. I had a slipped disc about 3 years ago L1 S5 and they said it was not linked to this because numbness in thigh would be linked with an L3 problem. It is particularly noticeable that if I stand on the same spot for 5mins or more, such as bird watching or washing pots, it always gets very numb. The last Neuro surgeon I saw said there was little they could do. They injected my thigh with something and it did nothing. I m not satisfied with this and wondered what tests could be done? It is odd that when my L1 S5 causes pain in my lower back (sometimes the disc still touches the nerve) it does being the numbness on in my thigh? Even though officially L3 is the cause of this, according to the Neuron surgeon I saw. Do you have any ideas? One of my legs is shorter than the other and I seem to have tight hamstrings. Thanks
