One Dr floroscope says hip is very bad. need replacement. Surgeon says hip x-rays normal. Now what?

I have a genetic disorder which has required several joint fusions and/or replacements. Having severe lower back/hip pain. Neurosurgeon (has done several spinal fusions on me in the past) says mylegram shows spine is OK. Probably hip pain. At Pain Clinic, Dr uses fluroscope to position needle for hip injection says hip in bad shade-will most likely need replacement. Go to hip surgeon who does x-rays- says hip is fine. X-rays normal. Effects of injection had been wearing off although very effective initially, Held off on more injections since Appt with hip surgeon was upcoming. Now hip beginning to hurt worse. What to do now???
