Looking for some helpful info to lead me down the right path. I started with severe pain in my left hip around the end of November. I could not lay on it, sit in a chair, and walking was not bad but still caused problems if I stayed on my feet for a long time. Then the pain I was having went into my mid to lower back and groin and down into my legs. The pain radiates from my left to my right side. (mostly in my left side) It can go from dull and achy to sharp and stabbing at any moment then dull back down again. The back pain is like someone is punching me in the back over and over again. I still am not able to lay on my left side or sit for extended periods of time. Prior to this problem, I was having numbness and tenderness in the back of my upper legs. I also experience a numb spot in my upper back on the right side between my spine and sholder blade. I have had x-ray on my hip and lower spine, I have had ultra sounds, ct scan, and MRI. Nothing is showing up. I'm getting very frustrated.
