Yes. Seeking treatment is allowed and encouraged, and it does not go against trust in Allah. The Quran forbids casting oneself into destruction (2:195). Treatment must not use anything haram if a lawful alternative exists, and haram medicine is allowed only in necessity.
Dan belanjakanlah (harta bendamu) di jalan Allah, dan janganlah kamu menjatuhkan dirimu sendiri ke dalam kebinasaan, dan berbuat baiklah, karena sesungguhnya Allah menyukai orang-orang yang berbuat baik.
