Pain on outer edge of foot

Hi! Currently training for the United Half and I’ve been experiencing some pain on the outer edge of my foot that I got after my Monday run. It hurts when I put weight on it and there’s also a sort of creaking (?) sensation when I flex my foot. No pain when I don’t put my weight or massage the area though.

I’ve been taking rest days and wrapping my foot and both the pain and creaking sensation have improved over the past two days but I’m not sure if this something that I should get checked out if I’m still planning on running the half marathon. Thanks!
