### Patient: I have an open wound on my arm, and I've been experiencing an elbow lump or mass, elbow swelling and hand or finger weakness. What could be wrong with me, doctor?
### Doctor: It seems like you have an injury to your radial nerve, which is causing radial nerve palsy. This is a condition in which damage to the radial nerve results in weakness or paralysis of the muscles associated with it, as well as reduced sensation in the arm and hand.
