My lower lumbar has a lot of pain also my left hip hurts. When I walk it s almost unbearable. If I stop and push my head up from under my chin or hang upside down my back will pop every time. But after I walk maybe 40 or 50 steps it feels like it goes back out of place, then the pain comes back. Been this way for the last 3 months. I got a cortiszone shot 4 weeks ago but it didn t do much good.
You are having limbo sacral radiculopathy.  Get your MRI LS spine done. Start physiotherapy.  Avoid bending forward and lifting heavy weight. Start tab praline once daily and analgesics SOS. Hope my advice will help you.  Take care. Don't forget to rate me.
