Eczema?

I’ve had an extremely sore finger for months and months now. It keeps cracking open/ peeling and bleeding. It’s very painful and as a result of the peeling it keeps hooking into stuff as well which is just further irritating it. I’ve seen my doctor and he said it was just hand eczema and prescribed a cream ( which has done absolutely nothing!.. I’m going to make an appointment and go back). I’ve tried polysporin and loads of different creams before the one he prescribed and nothing has helped. Has anyone had something similar? What worked?
