My Son Twisted His Foot While Playing

Hi, I'm Andrew from Toronto. My son is 13 years old and he loves Tennis. Unfortunately, he had an injury last month while playing.

He twisted his foot and we went to the doctor. He took the x-ray and told there is a hairline fracture. He advised taking complete rest for two weeks. After taking rest for two weeks, the swelling in his foot is now gone. But he still has the pain. When we took another x-ray last week, he doesn’t have any fractures.

So the doctor suggested a nearby clinic that provides sports physiotherapy. I don't know much about this treatment. Will this treatment do any good? Also please share your thoughts and other suggestions.
