Suffered displaced phalanx fracture 4 weeks ago. 5th toe is bluish black, feels detached & spongy. there is dull pain & unable to put last 2 toes down?

Stabilize.: Toe fractures can range from simple , straight forward to those of more severity. The recovery process, as you would expect, will vary depending on the severity and treatment. Your inability to pit your last two toes down, seems to signify that there is still some residual swelling. This is not too unexpected if the toe is unstable. This could best be remedied by taping the last two toes together.
