Im 19 and have been having exruciating pains near my right hip for over 2 months, it started as a rumbling uncomfortable feeling, but now it happens every day, normally at night time. i have cut out wheat from my diet it still happens. and have had lots of blood tests, my last one showing a raised ESR (something inflammed-that is causing the pain) the doctors are baffled, but i have tried to diagnose myself, thinking its either kindey stones, a type of cyst, however my doctor thinks its IBS which i dont agree with. any ideas PLEASE?!
