Lisfranc Sprain or Extensor Tendonitis

Hello all. Has anyone ever had a Lisfranc Sprain or Extensor Tendonitis. I irritated my foot a week ago while squatting down at work and arched my left foot forward This foot has been irritated before and healed fine on its own but it’s still sore, bruised and swollen a week later. The swelling has gone down some but the middle top of my foot is still sore. Will see a doctor to make sure it’s healing like it should. If you’ve had this how long did it take to heal? I walked around on it all day at work on Saturday now I’ll probably miss work tomorrow. TIA
