Supplemental claim to C&P exam

Filed in January for an increase in migraines. Denied and then spoke with my VSO and they saw that my migraine log was not even listed as evidence on my decision letter. He helped me file a supplemental appeal in May. ACE exam completed in late May and then played the waiting game. Fast forward to last week and VERA tells me it’s been assigned to a team…. Sitting around 108 days. A week later (today) I get an email saying the VA has scheduled me for another C&P exam. WTF?…

I guess I’ll have a chance to add more of my migraine logs to the evidence but does my clock start over and I move to the back of the line? TIA
