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.
Fazei dispêndios pela causa de Deus, sem permitir que as vossas mão contribuam para vossa destruição, e praticai obem, porque Deus aprecia os benfeitores.
