Maintain your posture while sitting standing and while working. Try to avoid uncomfortable positions. And for nurses while taking night duty in sitting uncomfortable position they used to sleep. This is also a cause of back pain. Have a regular exercise to strengthen your back muscles. For relieving pain syn Chat Doctor.  You can use a local anti-inflammatory gel of diclofenac or nimusulide also. And do a hot compress also. If you don't have any disc herniation or other problems this will help. Thanks
