My son has been put on steroids to clear his chest he is two yrs old but since taking these he has has three nose bleeds is this a symptom?

Unrelated: Nose bleeds in a 2yo are more likely to be a reflection of other issues.Nasal allergies, irritants, or poorly humidified environments all can irritate the capillaries in the delicate nasal membranes & kids often wake up on a bloody pillow having had a bleed in the night. Smoke from a fire, fumes, fragrances, etc are other aggravating factors.
