I have been trying for 3 days now and nobody seems to think it is a big deal. I have called SSDI office and explained and told if I cancelled it may be years before my case would come up again. I contacted my atty who said I have no choice but to go along with the eval and xrays. I have no idea what further xrays could be needed, had bone scan in late April and xrays in June...i really don't need more exposure. I contacted the physician's office where they have me scheduled (40minutes from my home and I am not allowed to drive) they were very sympathetic and would love to reschedule..but it is all up to the judge
