Hello, My name is Altafhussain. 10 days back I had a sharpa and deep cut at between metacarpophalangeal joint (MCP) and proximal interphalangeal joint (PIP) on my Left hand little finger. The wound has been heald. But I am not able fold my finger. There is always mild pain and numbness in the fingers. I can fold using other finger and it does not pain. But can't fold normally as other fingers. It seems my flexion muscel is damaged. Please help what needs to be done to bring my finger back to normal function.
