What Should I Do If Liquid Methamphetamine Spilled On My Foot, Solidified, And Is Causing Severe Burning Pain?

I m so ashamed to say this, but I accidentally poured liquid methamphetamine out of the pipe and on to the top of my foot. I know I need to wash it (seeing as the drug has solidified and is currently still on top of my foot) But it burns so So BAD! I m so stupid and in so much pain..
