I have horrendous left-side pain. From my mid-back, the left lower quarter & my left leg are often locked in severe pain. It feels like this area is 'foreign' to me. Like it doesn't belong. And the pain is terrible. Ordinary over the counter painkillers don't touch it. I had an MRI but they found nothing amiss. I did a years worth of physiotherapy but that made no difference either. Right now I have nothing bad going on in my life. I'm single, free & happy - apart from this terrible pain.
