It can be a part of myofascial low back pain or it may have happened due to incorrect leg lifts causing strain on the band
. Wrong sitting posture causing improper transmission of force and strain on the band
can bring about pain. Changing posture while sitting, using a good chair with back support, getting up and walking once in a while, etc helps. When in pain, RICE treatment helps (rest, ice, compression by wearing a knee cap and elevation of leg).
