Back pain is common among adults aged 65 and older. In this age group the cause of back pain is often linked to degenerative processes. The discs start to wear thin, bone spurs develop, and the spinal canal starts to narrow.
The forward flexed position opens up the space around the spinal cord and spinal nerves taking pressure off these structures and reducing painful symptoms. Sometimes exercise and anti-inflammatories can help. Surgery may be an option when conservative care doesn't work.
A medical examination may be needed to sort this all out. Find out first what the problem is in order to determine the best treatment. Early treatment usually brings the best results. Waiting too long may result in permanent postural changes.
