swollen big toe

About a month ago I dropped a metal table on my left big toe. It turned dark red and became swollen. It was only painful if I wore shoes. During the following weeks it has become consistanly painful,always swollen and very red (dark red). The weird thing is that the skin on my toe has become very thick. I have soaked and pampered my toe to no avail.Can you suggest a possible treatment to follow.Anyone!!!
