I had severe burning from 3rd week of 4 week photon radiation. I was peeing a lot of blood for 2 days. I was asked to take AZO first along with Tamsulosin for 3 days followed by just Tamsulosin for 4 weeks to slowly recover from burning. I tapered slowly the Tamsulosin 4 weeks after radiation. I have very little on and off burning. I was told to restart Tamsulosin in case burning recurred
