This is a small, colorful, jeweled doohickey. It will stick to most surfaces, and won’t come off until you pull it off again. Place the doohickey somewhere in your shower stall, and when you get under the water, it will wash physical pain away. Internal pain, external pain, all the same. Under the incredibly soothing waters of the pain shower, you will feel relief from all discomfort and pain. There are no side effects.
The water will make you clean, also, like any normal shower. When you get out of the shower, you will be pain-free for a while, and then the pain will slowly return over the course of a few hours. At any point, you may take another pain shower and enjoy the same relief.
