Hi I am 15 years old been experiencing severe lower back pain for 3 months right now. It has gotten so bad I have to be on a crutch. I have weakness/numbness and tingly on my left leg and it's hard for me to walk around and I have been very tired and sick lately. I urinate more than usual and I can't barely walk on my left leg. The pain goes from my lower back all the way down my leg. The pain wakes me up and night so I can't get sleep even if I try. I went to my doctor and my blood pressure was higher than it was suppose to be for my age so she referred me to a neurologist. So when I went I thought he was suppose to do a examine on my back and all the physical examines but he didn't all he did was test my reflexes. That's literally all he did and He ordered a MRI on me and he couldn't find anything. I was so surprised he did two on me one last week and one a couple days ago and still nothing. Idk what to do anymore. I get worse by the day and I can't do the stuff I used to anymore. I am very sick and in pain. It felt like he really didn't do anything and I am so tired I just wanna find out what's wrong. Help please?
