To make a long story short, I had problems with my neck and upper back, and legs after rear-end accident with semi-truck. Went to physical therapy for a long time. Have been going to chiropracter for over 6 months now. However, ever since the accident happened. I had lower back and leg problems. For the first year I would have extreme burning pain down both my legs front and back, in pain sitting or standing. I tried talking with doctors, was always passed up for muscle spasms. Now, 3 yrs later, I still have the pain, but also, numbness in feet, and my leg muscles including my gluteus maximus(burning pain there) are very fatigued. My mucles in my legs also twich frequently. It is almost impossible to walk up my stairs to the apartment. I limp almost everyday, and have fallen a few times. I did finally get in to Kaiser's physical medicine department once more, and they ordered an MRI on my lumbar region. I'm hoping for the results in a few days. However, my chiropractor believes this might be neurological(brain) and the MRI might not show anything. What do you guys think?
