If i remember correctly, I think Kuma actually battle using his paws; hence the Nikyu Nikyu No Mi. I believe the paws holds the power of his DF that's why he extracts pain by pointing his paws at Zoro and sends the SHs flying by hitting them with his paws. as to how he extracts pain from one person to another; i think it's not the pain that he extracts but the sustained injuries. as a result, it is normal for a person to feel "pain" after so many physical injuries during a fierce battle... Just my own two cents
