A sedentary lifestyle, bad posture, stress and overdependence on technology could leave you with a constant backache. But experts say sometimes the problem can be easily sorted out with the right diagnosis and a little care. Experts point out that the problem of lower back pain is fairly common. About 80 per cent experience pain at some point in life. "The major culprits of back pain, especially in young adults, is stressful and long working hours stretching up to 12 hours and more, lack of properphysical activity, bad habits such as reading while lying down, slouching in front of the TV, etc, coupled with weight issues," B.K. Dhaon, head of the department of orthopaedics at Sharda Hospital, said. What comes as a surprise is that fitness-conscious youngsters, who are regulars at gyms, also suffer from it. In such cases, bad sitting posture is often to be blamed, says Amit Kumar Mishra, an orthopaedic surgeon.
