Dermatologist told me Kenalog shots will not work on 1.2 cm keloid

Hi, I recently saw a dermatologist because I have a keloid on my third lobe that is about 1.2 cm, around the size of a pea. She told me that I should just consider removal as she doesn't think that shots will do anything and referred me to someone that could do it. Has anyone had any success getting rid of a keloid that size with just shots?
