I smashed my right little toe about 4 weeks ago, it originally turned black and blue, swelled up and hurt to touch or put pressure on. Till this day, it now hurts when i apply pressure to it or after a few hours of work it throbs, swells up and at points feels like it is on fire or a stabbing pain goes through it. Could it be broke, fractured or sprained? And what can I do at this point, i work on my feet 40+ hours a week. Thanks
