SSgt-USMC

Hi to everyone. I was put on the TDRL from the Marine Corp and rated 40% for unretractable migraines, neurocardiogenic syncope, and clusterheadaches in September 2008. I was subsequently given temporary 100% from the VA. I havnt been able to work since I was seperated from the service and I dont see myself being able to work at all due to the migraines, syncope episodes and meds. However I am in the vocrehab program and barely hanging onto that because of classes I have had to drop due to my conditions. Well the 12 months have passed and I have yet to hear from the VA for my exams and I was wondering if i should file for TDIU now? On my temporary 100% decision letter they acknowledge SC for my migraines, cluster headaches, syncope, allergic rhinititis and GERD so I am assuming I have the magic 70% to qualify for TDIU but not sure since I havnt had an actual exam. Also I am wondering why they havnt contacted me for my exams for the temporary 100%, assuming backlog or something. what shall I do? thanks in advance
