Facing problem (discomfort in left side, at the joining of abdomen and rib and sometimes in the back) during sleep, it's now almost 6 months. Earlier had UTI but can't remember any injuries (used to do some home exercises). During seating position also feel discomfort in the left abdomen and rib joining and in the left back. Holding left back and ribs also feel less muscular than right side. Kindly tell me probable cause and if homeopathy can cure it.
