How long until a burn stops itching?

I accidentally burnt myself on the foot with about/almost half a cup of hot oil and it's healing well, I treated it correctly (warm then tepid then cold water, burn cream, etc.) but it's just really itchy, I was wondering how long until it stops itching? The blisters are almost all gone, it's just slightly brown and red, the skin is still rough-ish to the touch but yiiah, how long until it stops itching? It's so hard not to scratch!! Are there any easy, cheap, at-home remedies to stop it itching? Help please!
