Staying in a pool for long durations of time can eventually cause the waterproof cast to break down. Pool chlorine can get trapped between the cast’s liner and the skin and can irritate the skin below the waterproof cast when drying. This natural water can have microbes or other bacteria that can cause issues for your skin or increase risk of infection. If your specialist has approved swimming in your cast, you can enjoy swimming in a pool, but steer clear of lakes, ponds, oceans, or other natural bodies of water. May I go swimming with my “waterproof” cast?
