What Causes Severe Pain And Stiffness All Over The Body?

one morning 3:40am my sister woke up to use the bathroom but
She could not get out of bed as she was in acute pain. she could not move her foot or body,until I hold her so that she could take step . She was unable to sit on the toilet seat, her back was to sore to sit all of a sudden . it was very painful- with every motion of body she would scream and cry. She felt severe pain in her right side of the body: starting from nack, shoulders, chest right arm Back lower and upper, hips , lower abdominan , thigh, leg and even foot. For seven days and six nights it was difficult to sit stand or even lie down without pain. what does these symtoms alarm for?
Back ground info: She had chiropractic treatment previous evening and she was feeling fine. she moved light weight boxes while fixing and organizing the house and she was allright before she went to bed around 1:00AM She has been healing very well after an auto accident that happened 11months before. She is a healthy, active woman. could you think of any up coming health problem ?
