Hi I am Chat Doctor. .  In my opinion it could be a kind of sciatica due to nerve compression thus causing this kind of radiating neuropathic pain.  Of course lack of exercise, bad sleeping or sitting postures, heavy lifting, vigorous movements, can cause that kind of pain but don't worry sometimes it subsides simultaneously. You may begin with spinal straightening exercise, physiotherapy, hot massages with topical gels and even yoga helps. Use painkillers like Advil tab when needed, B12 vitamin supplementation, muscle relaxants will be effective for now.  If pain persists I may recommend further imaging by MRI and a neurosurgeon point of view for proper evaluation and management.
