About three months ago I had a lower lumbar sprain at work. I was out of work about 6 weeks, went through physical therapy. I was not completely healed when I went back to work. it was still very stiff and sore in that area and I was still having muscle spasms. so on Dec. 12th, I went to work still having soreness and muscle spasms. I felt a snap and found out my hip was broken. could this 1st injury have caused it. ive tried loading xray and cant. but I felt it happen at work. displaced, stable
