Hi Glitter1357
If you think your condition has improved in a way that affects your award then you are supposed to inform the DWP.. It is always difficult for claimants who have conditions that deteriorate at a moment's notice, and some people would inform the DWP immediately and others would wait to ensure they are stable. I can only tell you what the DWP say - which is that you should inform them if your condition has improved.
