Suggest Remedy To Relieve Pain In Right Hip And Sides

My right hip and side hurts a lot.. i went to the hospital and they did a blood and urine test and they said everything is ok.. i don't have any fever or vomiting but my right leg's pain is getting worst with my hip.. my doctor said it's not my appendix but they think it's something with kidney and they gave me medicine and nothing works with the pain.. the pain had been hurting me for a week now. i am a 16 years old female. thank you very much.
