Her back pain could be due to muscle strain or disc lesion. I would like to ask few questions whether the onset of pain is gradual or sudden? How long she is having pain?
Next Steps
She should give hot water fomentation for 15-20 minutes twice a day for a week.
She can use Volini gel or spray provided she is not allergic.
She should avoid lying on her tummy, instead she can lie on the sides or on her back with pillows underneath her knees.
She should avoid prolonged standing or sitting, she should keep changing her posture for every 20 minutes.
She should avoid bending activities and weight lifting.
She should do back stretching and strengthening exercises with proper guidance.
Health Tips
If the pain persists or aggrevates she should consult a Physician or Physiotherapist or Orthopaedist for further evaluation and treatment.
