Worst UTI of my life!!!!

I've had it for 2 days so far and the soonest I could get into the doctor is tomorrow. Please does anyone know any home remedies that will soothe this terrible pain? It is so itchy down there and burns like hell, I know better not to itch it so I've been keeping a cold rag on it and drinking lots of water trying to flush the infection out. Is there anything I can buy at Walgreens that can make this better for me!!????
