Admittedly, there are few things more maddening than having an itch that can’t be scratched. People with casts have been known to improvise a variety of tools to reach and eliminate the itch: pens, tongue depressors, coat hangers and other household items.
The problem is that these approaches can create an even worse problem. If the implement breaks the skin, there’s a good chance the wound will get infected. And, because the infection is concealed by a cast, it may not be readily apparent to the person. Needless to say, this is not a good situation.
The best way to treat the itch is to find safe ways to dry the moisture under the cast. Talcum powder can be very effective, though a tight cast might make it hard to deliver to the itch. Another recommendation is a hair dryer on the cool setting. This will dry out the area and, hopefully, relieve the itch. It is critically important to set the hair dryer to the coolest setting; otherwise, there’s a burn risk.
At night, Benadryl can also help control the itch. Benadryl doubles as a sleep aid and can help people avoid scratching in their sleep. Of course, because Benadryl does make people sleepy, this solution is not recommended during the day.
