Hi Dr Prasad,
My son had an ankle injury and was advised a plaster . We were also advised to avoid the plaster from getting wet or if he must take a bath, he could use a plastic cover over the plaster. We used a plastic cover over the plaster, but unfortunately the water went inside. Within 3 days my son started complaining of itching iin the feet. I insisted that the plaster be cut and to my horror, found that his foot was completely soddened . The doctor then advised us to leave it open. It has dried up, but i still need to know, if he needs to apply some medicine on the infected part or should he just let it be.
