I ave a popping sensation in my left lower to middle back when I lie down. I have persistent left lower back pain. After the popping sensation, I have a second of sharp pain followed by temporary relief of the pain. It feel like there s something caught, prior to the popping sensation
Hi I am Chat Doctor. .  In my opinion I think you may have a kind of severe muscular spasm or tendinitis that may cause such popping sound.  You may avoid further heavy lifting, overweight, vigorous movement and bad sitting or sleeping postures.  In mild cases physiotherapy sessions with a chiropractor, hot massages and spinal straightening exercises will give best results even without any medications.  For my patients I recommend painkillers like Advil tab when needed, hot gentle massaging with topical anti-inflammatory gels, muscle relaxants, B12 supplements will be effective for most of the cases , in more severe cases steroid tabs or injections may be needed.  If your pain persists I recommend MRI to exclude any disc herniation or spinal deformity and follow it up with your neurosurgeon for proper evaluation and management.
