Years ago a dr. Said I have lower lumbar strain. I had and have spasms in my lower back, stiffness , dull pain and spasms in my lower to mid back. Also, often when I lay in bed in any direction my back just akes and parts of my lower back feel like it is literally ready to crumble.I have a pulling sensation and sometimes numbness in my lower back and butt when crossing my legs and laying down or bending. Also, a few years after my diagnosis, I started getting pain running down my butt threw my legs. Another said this is sciatic nerve problem. What do you think is going on with me and what is the prognosis for the future in your opinion? Also, do you have any suggestions for me?
