your profile type L is low, which means you have least potential for medical improvement. The 7 year review means you're Medical Diary Reason is MINE, which means medical improvement not expected. Your profiling score going down by 21 points means that due to increased age, or increased severity of your illness or some other reason they think that you are less likely to improve than they did when they sent you the last mailer 7 years ago. The numbers for the profiling score go up to 9999, so your number was pretty low already 7 years ago.

All in all, if you have been going to the doctor and have not improved or started working again, you have nothing to worry about.
