Replying to Ingrown toenails and ski boots

Now I've had ingrown toenails for most of my life and usually they're pretty bearable, save basketball shoes and ski boots. Now last year I started skiing and was fitted too large by the boot fitter(can legit move my foot back and forth inside when buckled) so today I went to a early season expo and picked up a new pair of ski boots. They are very snug and fit we'll but my only concern is my two big toes, because of the pain in my toes along the outer edges. They hurt quite a bit when stuffed inside my boots but I definitely do not want to size up as when it packs out, I will have the same issue as my old boots. Can I fix this by just bringing the boots to the fitter and having the toe box blown out a bit?
Thanks in advance to all
