I have been cleaning the wound with soap and water. I also applied neosprin to the wound and a bandage with gauze wrap around my thumb. I think I might of cut a nerve and an artery from the knife. Now my thumb has been numb ever since it happened. This is the third day and I haven't seen any doctor yet also my thumb can barely bend. Is there any possibility that I will regain feeling or complete movement in my thumb again if I don't get it stitched or surgery hasn't been done it? Please help my hand is opened really wide.
