Suggest Cure For Severe Pain In The Hip

hi i have a very long case but in short i suffer with cystic fibrosis and RA taking various meds to treat. Recently they have stopped me taking leflunamide because I came out with a rash , since then which is about 5 weeks now I have been coming out in frequent painless bruises especially if I have taken alcohol, also for about two weeks I have been experiencing hip ache which has become so severe that I making me cry an I am unable to walk properly or drive. My doctors know about the bruising and have not suggested anything useful. I have not been able to tell them about my hips but i really am in agony and need to know what to do ?
