Inspite of all, i would suggest do slight stretching exercise of all hip and back muscles (Iliopsoas, hamstring, quadriceps, glutii, abductors, adducdors, erector spinae, abdominals etc) but preferably in guidance of expert along with do light strenghtening exercise too ... not go for massage...
Hope for you get some help..
