Sir. I fallen down 35 days ago and injured in back side near lumber vertebra reason. I feel pain only when I go to sleeping position. Or lifting heavy wgt. Or when I tried to standing from sitting position. But I do not feel pain during running, bike driving, walking. Today my doctor saw my x-ray. There was no any bone and lumber spine injury. He prescribed me some medicine. I want to know the actual cause of this pain that I feel only in some specific angle of moving. But not feel in rest position.
