If my blood and 24 hr urine cortisol levels are normal is it still possible for me to have Cushing's? I have almost all the symptoms.

One more idea. You may be a candidate for a low-dose dexamethasone test. Remember that the large majority of folks for whom Cushing's is a serious consideration turn out not to have it. In the meantime, I hope you're finding time and opportunity to pursue physical fitness activities. Best wishes.
