Our expert says:
There are so many different structures that could be involved, it would help to know which side of your foot turned blue and swollen. Anyway, if that area is still blue and painful after 3 weeks it should be properly checked out. It could be anything from a fracture to a sprain, I suggest you go and see a physio who will be able to make a diagnosis or refer you for the appropriate tests. Voltaren Gel will help with the swelling and pain.
