Thanks everyone for the advice, I took some pain killer and have my hand
sitting in a metal cup of freezing water which i change when it starts to
warm. Its still pretty sore but no redness or blisters seem to be
appearing. The skin is just white. I am forever burning my self in the
kitchen tbh, but although this is a tiny burn it is by far the most painful.

Think I'll be sticking to salads over the summer )
