VA 21-526EZ

Due to a heart attack and a pace maker since  being service connected, I would like to request a review for  a rating increase.  Because I had heart disease and diabetes at the time of original filing, some people were surprised I did not get a 100% rating instead of 70%.  Maybe the heart attack and pace maker will put me to the 100% mark. 

Also would like to file for a new condition.  I have developed hand tremors and to a certain extent upper body tremors.  Makes it difficult to function on a day to day basis especially eating. 

From what I have read you use the 21-526EZ for both the review and the new condition.  Can I do both on the same form or do they each need a separate filing?

Thanks in advance.
