I have had a pain in my lower back on the left side for a few months now.  A couple days ago I turned wrong and it felt if I had pulled something in the same spot.After a day of rest, I was able to resume normal activity, but I still have the same dull pain.  It gets worse when I sleep, but is better the more I move.  Is it just a pulled muscle that will not heel?  Or something to contact my doctor about?
Hi, With above clinical picture I am inclined to think in terms of Left Sacroiliacs -- Inflammation of Sacroiliac joint. I Suggest Pain killers SOS, and Spinal Extension Exercises on regular basis. Hope I have answered your query. Let me know if I can assist you further.
