Hello. This is my first post to spine health, I'm looking for some help understanding my injury, hopefully I've provided you with enough of a backround. I'm a fit 29 year old male. I injured my back around 3 months ago lifting something heavy. Since then I've had constant lower back pain which is stiff when bending backwards, the pain is slighly more to the right. Along with this I've had sciatica running from my right buttock, down the back of my right leg, all the way to my foot, which is making walking difficult. I also have a little sciatica down the back of my left leg, but not as bad as the right. Also I've got parathesia in my perineum area, and the tip of my penis. The sciatica is made worse when sitting, especially driving which is near impossible for me. I've had an MRI which my physio looked at, and it shows no herniated disks in my spine, and he said he has no idea what's causing my pain, and that he cannot help me and I have to live with the pain. I wondered if anyone has suffered anything similar? I'm really at a loss about what to do next, my doctors have basically written me off and it's really affecting my mood.
