To treat a rash caused by friction from wearing an arm sling, first clean the affected area with mild soap and water, then pat it dry gently, and apply a thin layer of petroleum jelly or a zinc oxide cream to create a protective barrier, as these measures can help reduce friction and inflammation, and are recommended based on general medical knowledge and principles of wound care 1. When treating the rash, it's essential to avoid using topical antibiotics like bacitracin, as they can cause allergic contact dermatitis, with studies showing that bacitracin is a common sensitizer, with 44% of patients testing positive to it 1. Instead, consider using over-the-counter hydrocortisone cream (0.5-1%) applied 2-3 times daily for up to 7 days to reduce inflammation and itching, as it is a relatively safe and effective treatment for mild to moderate skin irritation. To prevent further irritation, take steps such as:
- Placing a soft cotton cloth or padding between your skin and the sling
- Ensuring the sling fits properly without excessive movement
- Keeping the area clean and dry
- Allowing the skin to breathe periodically by removing the sling for short periods if medically permitted These measures can help reduce friction, prevent further irritation, and promote healing, as supported by general medical principles and practices. If the rash worsens, shows signs of infection, or doesn't improve within a week, consult a healthcare provider, as you may need prescription-strength treatments or further evaluation to determine the underlying cause of the rash and develop an effective treatment plan 1.
