Faulty posture is a major underlying cause of back pain. It can alter the normal curves of the back and put severe stress on the muscles and ligaments of the spine. This can be provoked by standing for long periods with back arched or sitting in a slumped position. In females, backache is mainly noticed during pregnancy and menopause due to certain hormonal changes. And although cancer of the spine itself is rare, it is possible for cancers in other parts of the body to spread into the spine damaging the bones and producing backache.
Degenerative changes are also causes of backache.
Although your back is designed to last you a lifetime, it will get weaker as you get older, and the weaker it gets, the more vulnerable it will become to damage. Not all backaches are caused by injury, degeneration or old age. There are numerous individual disorders which can affect your spine like osteoarthritis, rheumatoid arthritis, osteoporosis, osteo-malacia, ankylosing spondylitis, sciatica and Paget's disease. Lastly we must not forget that emotions affect our muscles. The two are bound together.
