I am currently waiting MRI results. I have had a normal x-ray. About 7 days ago, I went to bed with a back ache in my lower back. The next day, by 5 o'clock I was crying, in so much pain that I could not walk or lift my legs. I was scared. The next morning it felt a little better, but by 5 the next say..same thing. At first it was a sharp pain in the base of my spine, then it moved to the left. Now, I have some pain down my left leg and in my hips, and a little of the sharp pain is left. But, when I walk is when the problem really starts....I cannot stand completely upright and as I walk, the muscles in my back become so tense it takes my breathe away. I have to hold onto something and gasp, like my muscles become frozen. Once I sit, they spasm for a while, but relax and the pain is moderate. I am having a hard time functioning, not being able to walk or stand for more than a minute at a time. What cousl this be?
