My sweet seven year old female schnauzer hurt her front left toe two weeks ago. It bled and she limped for days. Now she is licking both of her front paws constantly. What is wrong with her?

Please help! Izzie, my seven year old schnauzer hurt her front left toe two weeks ago. It bled and she limped for days. Now she is licking both of her front paws constantly. In addition, she was diagnosed with schnauzer bumps. What should I do?

NOTE FROM LINDA AND MAX: The injury may have triggered her constant licking. One solution would be to put a plastic E-collar on her so she can't lick it for a couple of days.
Schnauzer Bumps are not serious, they are just like human blackheads.
