Hello there...I can understand your concern. Backache at your age could be due to many reasons like osteoarthritis, osteoporosis, disk prolapse, trauma, muscle spasms. You will need detailed clinical examination and further investigations. Associated vitamin d deficiency and calcium deficiency might be exacerbating the pain. So kindly consult a orthopedic for further evaluation.
