I think I have ulnar nerve damage! My pinky is numb and tingling and the side of my hand is numb. My ring finger feels heavy and weak. I put ice on b?

Ice on b? Without knowing more information I cannot affirm whether your ulnar nerve is damaged. What is the mechanism of injury? How long have you been having the symptom? What makes it better or worse? Also, I am not sure what your question is. What do you mean when you write: "I put ice on b?" Please clarify. Best wishes.
