Thank you very much. I will take a look at these!

Just keep it short and to the point- highlight how it affects you in a meaningful way without too much vagueness. If you can't walk more than 50yds, say that with an example. If you can't drive because of drowsiness, or have fallen asleep at inopportune times, give examples. If you have guy/girl problems, briefly indicate how/why they are worse or what they relate to (pain, lack of performance, discharge, stuff like that). All of this makes it easier for us to find it in your records. Certain medical words jump out at me when I read through these, and these are the words I start with doing CTRL-F searches through your medical stuff. Don't self diagnose yourself or go to Web MD to look up what you think you have. Just call it whatever your doctor does. 
If you have some dates of treatment at various places that are not VAMC make sure you have a 21-4142/21-4142a filled out with those providers so the records can be requested. There isn't a format- its in your own words, just give a good summary of whats going on with each disability are claiming for increase.
If you are submitting your own private medical records, be a dear and highlight or write in the margins or something for the high points (images, diagnosis, relevant Dr. Statements, etc).
