ask your family doctor to get you a referral for mri. They will do that. I had same problem found out i have serious lurabar disc disease and a tear in my spine. it will get worse as has mine. all I did was tell my family doctor that i needed a referral to a pain doctor and was in pain management within a few weeks. I waited two years suffering because I did not realize all I had to do was ask my doctor to do these referrals. i thought it would be a big deal. but it is not. I have pain in both legs. the pain when you stand is pinching of the nerves in your lower back and you need to know the cause and how serious it is - dont wait like i did.
