Left Shoulder Pain with numbness in right hand since a fall.

Patient: My husband slipped on wet back doorsteps a couple of weeks back.When he slipped he said that he came down on his left hand and it felt like he pushed something up in the shoulder.HE heard something make a crunching sound.Now the pain can be excruciating.I told him he may have sprained or cracked something. He has also been having numbness in his right hand now.He’s very stubborn and will not go to the ER because we have no insurance.Thank YouBelinda
