I have pain in my left toe and some redness on top. pain is unbearable the first days i couldn't walk and felt like it was broken?

Varies: Did you injure it with a mechanism of injury severe enough to cause a break. Has there been anything rubbing against it to cause a pressure sore or callus? Is there any sign of infection like drainage from it it redness spreading up the foot? A detailed exam and appropriate studies would likely reveal the cause and the appropriate treatment.
