<s>[INST] hi my daughter fell on her elbow couple hours ago and she said all her arm is numb and shes holding her arm up, it hurts to move it back down, and when she moves it down a little bit she can hear a crackling noise, and she said her elbow made a clicking noise when it happened. ive compared both arms and nothing looks broken. just worried about the numbness? could she have hit a nerve? [/INST] Hello, There is a nerve called ulnar nerve which is in the elbow and any time you hit the elbow can hit the nerve as it is very superficial under the skin. It is like an electrical shock, the moment you hit and can feel the numbness. The numbness should go away within few hours. If your numbness continues the next day you should see the doctor as you may have a bone crack or fracture. I wish you quick improvement. Hope I have answered your query. Let me know if I can assist you further. </s>
