This is something which we are not focusing in our daily life but can produce multiple problems in spine especially for those who have a long sitting hours. Make sure that when you sit in your office chair your valet should be not in your back pocket.
Your wallet can be real pain for your back and the buttocks, and it can even lead to shooting pains down the legs. Sitting on a wallet for prolonged hours every day can compress sciatic nerve which passes beneath piriformis muscle and leads to piriformis syndrome, low back pain & self-inflicted sciatica.
The wallet acts as a wedge that forces the pelvis, spine and body out of alignment. Just as you would not sit on a brief case or a rock for an extended period of time, you should not sit on your wallet. Anyone who drives more than a half hour sitting on a wallet is a candidate for sciatica or back pain.
The healthiest option is to move the wallet to your front pocket. If it’s must to keep your wallet in your back pocket, you should remove it before you sit down.
You will immediately have a feeling of enhanced well-being, knowing that your pelvis is perched on a level surface and all the musculoskeletal structures above it are better off for your effort.

还好，女人们都是把钱包放在手袋里。
