Back sprain means injury to the ligaments or the muscles of the back. It can usually happen due to certain activity or may be with a fall or accident. The underlying cause of a back sprain may be weakening of the muscles of the back which may predispose the person to develop back sprains. If a back sprain is recurrent, then they may need physician medical attention to take care of their back so as to prevent further recurrences.
An episode of back sprain can usually be treated with short term rest for one to two days along with anti-inflammatory medications and use of ice or heat to decrease the pain. This should be followed by usual activity as well as exercises involving strengthening and stretching of back muscles.
