Hi there Sorry to hear about your troubles. A persistent itch must be extremely frustrating to put it mildly. This along with the lack of support from your gp must be making things worse.
A couple of things relating to steroids. They will cause your blood sugars to rise. This will resolve once you stop them
In addition check whether you have to stop prednisoline completely or decrease it slowly. This is likely to depend on how long you have been on it you.
Hope things improve soon
