An x-ray might be helpful to see if the toe is healing properly. I always splint the toe to the next, using a foam pad inbetween the 2 toes for support and cushioning. I also use a hypoallergenic tape and carefully show the patient how to redo this. I generally recommend taping for approximately 6 weeks. It is amzing to me how many people think "there is nothing that can be done for a broken toe." The foot is the only part of the body that when it is injured everyone expects to be able to walk on it. It is as important to allow these bones to heal as any others.
If you are not comfortable, see a podiatrist.
