i HAVE A LARGE MASS ON THE UPPER SECTION OF MY RIGHT BUTTOCK THAT WRAPS AROUND TO ME HIP. I HAVE PAIN THAT SHOTS DOWN MY LEG, UP MY SPINE, IN MY HIP, IN MY LOWER BACK. IT IS VERY HARD AND PAINFUL TO BEND OVER, SOMETIMES, SIT, WALKING, OR EVEN SLEEPING.
I STARTED ASKING DOCTORS QUESTIONS TWO YEARS AGO WHEN IT WAS A SMALL LITTLE LUMP AND I STILL DONT KNOW WHAT IT IS , MY NEOROLGIST HAS STEPPED IN AND STARTING TO ORDER TEST BECAUSE OF THE SIZE IT HAS GROWN TO.
