I have recently started suffering with lower back pain/Nerve pain. I have been getting numbness in my right hip . My toes on both feet are freezing. Has anyone experienced this before??

I have in the past have a slipped disc. I solved that by seeing a physiotherapist (as much as I can). I do a lot of Pilate's and walk between 3-6 times a week. This has helped so much in the past and I would like to recommend it to everyone. I'm always so careful with my back and find it so frustrating that this has happened again after being just about pain free for over a year.
