A sharp steak knife pieced to lower thumb quite deep, can not move upper thumb joint and feels numb.  How soon after the accident must I have a hand surgeon work on either repairing tendon, and nerve, and, after the surgery, how long does it take to heal completely, with therapy.
Hi, there! This is urgent situation! You have to go to emergency as soon as possible! Recovery after surgery is approx. 6 weeks (splint) and physiotherapy after all to restore range of motion. I hope this helps
