Welcome to Healthcare magic forum,
Do u have pain in lower back which radiates to leg? do u hv pain in neck also?
Less space in spines indicates the disc bulge or prolapse which is causing the symptoms, to get clear detailed diagnosis pls get MRI
scan of the spine and consult orthopedic doctor for proper treatment.
Meanwhile few advise to follow, dont ride 2 wheelers, dont life heavy weight, sleep on flat surface, no sudden bending and turning, give hot fomentation.
All the best,
Hope I have answered ur question.
