Pain when I flex my fifth toe

Hello,

About a month ago I hit the wall with my right fifth toe while playing
squash. Is wasn't too painful and kept playing. But 2 weeks later I
started to experience some pain when flexing the toe. It's been 4
weeks now and the pain is increasing. If I touch and manipulate the
toe there is no pain at all, it only happens when I flex it and even
more when I apply resistance when flexing.

Any guidance would be much appreciated.

Thanks,
Guillermo
