My 28 yrs old. For the past four months I have been having a dull achy pain on the right back side between my ribs and hip and inside my right hip area. It does not hurt to bend to the side, but it does hurt to bend down and sit or stand for too long. I drink more than 8 glasses of water a day and do not have fever, problems with my urine or bowels. I had my tubes tied in 2004 after the birth of my fourth child, so I know I'm not pregnant. The pain is steadly getting more painful. Any help?? Please.
