are all stutters treated the same?

are all stutters treated the same? i have a stutter that causes me to make a ¨ugh¨ sound that is forced. its really hard to explain the sensation but it feels like a muscle spasm in my throat and forces the sound. sometimes this causes my head to hurt. i am worried becuase when this happens people think i am having a siezure. i have not been able to find what triggers this, it just happens randomly, sometimes more than other times. . i want to try to fix this but i need to know where to start
