I HAVE SEVERE PAIN FROM MY RIGHT FRONT HIP OR TOP OF MY RIGHT LEG DOWN THROUGH MY LEG. THIS PAIN IS SEVERE, I HAD X-RAY, OK, BLOOD WORK OK, MRI, OK CAT SCAN OK,SO WITH ALL THAT, I STILL HAVE THIS SEVERE PAIN. DOC PUT ME ON GABAPENTIN, WHICH SO FAR HAS DONE NOTHING. IS THERE A GOOD MEDICINE TO STOP THIS PAIN.... LORATAB, ULTRAM,OXICODIENE AM ALERGIC TO THEM..... THANKS
