<s>[INST] Hey, so last week i crashed my longboard and it was pretty bad. I had tons of pain and my arms were pretty banged up. About two hours later i noticed that i had little to no flexibility in my left arm and hurt to move it. Now i have almost all my road burns healed. But my left arm is still weird. I cant fully straighten it and when i do a bicep flex without flexing (if that makes sense) i cannot pull my arm towards my self. What do you think.. [/INST] Hi, thank-you for providing the brief history of you. A thorough neuromuscular assessment is advised. As you are not able to flex the elbow actively you need a thorough assessment. Due to pinched nerve there leads to certain weakness and early detection helps for further management. If the injury is happened by the fall on the neck directly an MRI or NCV will be advised and post which the medical management will be directed. Also, post these if the injury is minimal then with rest, medication and physical therapy you should respond well. RegardsJay In Chat Doctor.  </s>
