Welcome to the forum.

You might be one of the many people who have problems when they approach the 7 mg dose of prednisone. You certainly wouldn't be the only person that has problems as you taper down to 7 mg.

My problems would start at 10 mg and get worse with every 1 mg decrease until I got to 7 mg. At that point I would go back to 10 mg. For me it wasn't only a PMR problem. I had a problem with adrenal insufficiency.

You may want to try tapering by .5 mg (half a mg) increments instead of 1 mg increments. It is rough going when we get into single digits of prednisone.
