Have you tried Imitrex or Furiocet for migraines? They work for me. Are the aura migraines when you see flashes of light with no actual headache? My mom used to have those, if that is what the aura means.
I give you a lot of credit, for all you are going through, and still have the strength to help another, your stronger than you think and have a heart of gold.
Hang in there......there is light at the end of the tunnel.
