Re: Modified Brostrom-More pain after cast removed
The boot allows more movement, so maybe that's what is causing the pain. Also, I found that sleeping in the boot was more uncomfortable than sleeping in a cast. You might need to loosen up the straps on the boot at night. It could also be the shift from NWB to PWB.
Definitely worth a call to the doctor, though, as even if those things were causing pain, you'd think it should be getting better after 5 days. Also, it's a long shot, but increased pain in your calf after immobilization could be a sign of a blood clot.
