Ingrown hair...underarm?

hi

im pretty sure i have an ingrown hair under my arm.... and its pretty deep. how would i prevent them? how would i treat it? do i go to a salon or something to have them take it out? if i tweezed my hair would it increase the chance of an ingrown hair?most importantly HOW TO TAKE IT OUT???? = [

thanks in advance

unlikely to be an ingrown hair,just shave it off.
