Persistent pain has been there since last 10 days. It originates from tip of the spine(probably last vertebrae bones in the spine) and radiates to above the left buttock. Gets aggravated with physical activity, and bending forward/down. Has trouble getting up from bed on her own when the pain is there, and pain is increased while walking too. Resting helps, and pain usually goes away after a nights sleep on hard mattress, however returns if any physical activity involving/stressing lower back is done. Pls suggest.
