Five.

          A slow, quiet thunder
drum, drum, drum
          deep behind my skull
pulse, pulse, pulse
           a threat to my mind
thump, thump, thump
           louder and louder
clang, clang, clang
           until it's a full percussion line
boom, boom, boom
           and I'm drowning in rhythm
cacophony, discord, bedlam 


I am just a heartbeat, a gasp,
just the pain that these migraines bring.
