Ligament injury on left wrist. The same.

Dear Dr, One month back I got injury on my left wrist while driving bike. I got the injury due to my need for applying sudden break which resulted in sudden right side twisting of my hand. I had no visible injury or inflammation or any lingering pain but I could not move my wrist side to side or up and down. While doing that , the joint area hurt a lot. After consultation, I was told to use a hand brace for 3 weeks as apparently I have a ligamnet injury. It's 5 weeks now and the pain had reduced significantly while moving hand, but I still have slight discomfort doing things like driving or typing in a keyboard. I wanted to know how long such injuries last and do I need additional treatment. Kindly guide me for the same. Regards
