I had lowe back pain a month or so ago and it had come on all of a sudden. The doctor said it was probably just a pulled muscle and gave me a steroid and exercises to do. Pain subsided after a week and all was good again until today. I was walking down the stairs and as soon as my foot hit the first stair, instant burning and pain in my lower back again and now I can hardly walk without being in severe pain! Ibuprofen isn t even touching the pain!! Is this something that I should have checked immediately or is it going to be another wasted trip to the doctor??
