This is my first post. I am rated 70% overall, 50% for migraines, 30% for shoulder, and 20% for back. This rating came in mid-november 2015 and I immediately applied for IU. I had another set of C&P exams that were requested and performed only four months after my original C&P exams in August. My veterans representative has sent me copies of all three C&P exams. The exam for the back has rom that is more restrictive then the original exam. It says that flexion is now 0 to 30 degrees, and extension 0 - 10 degrees. The first back exam said 0 - 40 + 0 - 15. The shoulder exam was unchanged. The back exam also says "veteran is unable to perform both sedentary and manual labor due to rom and pain." The shoulder exam says veteran unable to do manual labor, due to pain and limited range of motion, especially unable to do any overhead lifting. Now the migraine exam is the one I have a real problem with. My first migraine exam said veteran has frequent and prostrating migraines 2 - 3 times per month, & I saw the second exam and the boxes were not checked for prostrating and frequent migraines. These exams were all performed by a different doctor than the first exams just four months earlier. The back and shoulder exams that I just had we're by an orthopedic surgeon at the local VA hospital. The 2nd migraine exam was performed by a retired radiologist who is under contract to MSLA. So my question is, can the VA reduce my migraine rating based on the more recent exam, even though I told the examiner that my migraines have gotten worse and are prostrating and frequent? And a second question is, since the DBQ on both of my back exams both said that sedentary and manual labor was not possible, are just those exams enough to award IU?
