Physiotherapists have coined the term 'wallet-neuropathy' for the lower back pain caused by men sitting down (such as when driving or in the office) on wallets always carried in their back trouser pocket. 

理疗专家发明了“钱包神经病变”这个词，用来指人们的裤子后口袋有钱包时坐着（比如开车或在办公室），所引发的下背部疼痛。

The condition is triggered by the wallet pressing on sciatic nerves in the back and can lead to pain or numbness in the lower leg, ankle or foot. 

这种情况是由于钱包压迫背部坐骨神经引发的，可能会导致下肢、踝关节或足部的疼痛或麻木。
