Hello guys I hope you can help me. I filed my claim before I was medically discharged . At the time my ratings were 100 VA/ 20 dod. I had a few things that were 50% or higher. Well my doctor told me to asked for increase for the medical condition rated 20 percent . Well I just got their decision back and they have made my 20 percent rating 100 percent just by itself and also approved me for Special Monthly Compensation as well. They say my special monthly compensation start date is May 1, 2018. It’s says amount of monthly entitlement is 3,494.51. My question is will I get back pay for my special monthly compensation start from May 1, 2018 until now and is this amount of 3,494.51 will I get that monthly . Also no that my rating for my disability that was the reason for my medical board the DOD and VA only gave me a rating of 20% and now it has been upgraded to 100 percent. What benefits do I get now. What extra do I get that so don’t already have. And yes I’m P&T disabled
