First I'd say that many doctors don't understand PMR and falsely believe it only lasts two years. Unless they work with you on tapering, they're likely to have you taper too quickly. But, in your case, your doctor may have been thrown off by your age. The average age of onset is 72 and I think it's more common in causcasians so you don't fit the profile. All of us need to do our own research so that we can advocate for ourselves. So sorry that you are dealing with this.
