It is vital that you make it to 20 years of service. That aside, at a minimum you should be rated at 30%, but it seems that you more appropriately fit the criteria for 50%. That is based on the rating criteria for migraines. Depending on the facts of your case, you may have a basis for rating under other criteria.
I hope all goes well and that you get some relief from your migraines.
