Confidisc simplifies proceedings
Unfortunately, it doesn’t look as though the Confidisc will make injections with a hypodermic syringe any less painful than before. The Confidisc is actually a plastic disc that fits over the needle of a hypodermic syringe, blocking the view of the needle. This claims to psychologically reduce the pain perception that is often associated with self-administered injections. You can choose from one that fits over a syringe or another that has already been molded onto the syringe itself in order to intravenous drug use.
