Arthritis
If you are over fifty there is a good chance that eventually you will develop arthritis, It can be extremely painful especially if it effects your back.
It can strike many parts of the body including hands, arms, and legs, which can make walking or doing jobs you normally do a real effort.
Children can suffer with arthritis as well as adults but it gets more common the older you get. An accident can cause its onset as well. Exercise is quite important for arthritis suffers to stop the joints from stiffening even further, swimming or gentle cycling is good also walking.
Your weight can be a big factor, try healthy eating to regain your normal weight, and don’t go in for heavy lifting or moving large objects, especially if your back is the main problem.
Be careful stepping off buses or getting down steep steps etc, the jarring does your joints no good. It is a help to wear shoes with a thick sole as they can act like a shock absorber to the pain department.
Bending can be equally painful, I have one of those grabbers on a long stick and it is a god send for picking up objects that have fallen.
Physiotherapy may be a help for you, they provide you with a gentle excercise routine, but pain killers help a lot just be sparing in the taking if possible.
I also have a tens machine from the pain clinic, it does provide you with some relief from the pain. A heat lamp can help as well, or even a hot water bottle but the electric pads that massage your back and provide heat are good, you attach them to your chair and it helps to relax you. Of course you can buy the chair that does the job, but they can be expensive.
