While VR has been used mostly for pain management, there are a number of other ways that it is being used in medicine. One example is using VR to help people with phantom limb pain. This is where people who have lost a limb still feel pain in the missing limb.VR can also be used to help people who suffer from things like post-traumatic stress disorder (PTSD). It can also be used to help people with phobias, such as a fear of heights or public speaking. PTSD and phobias are usually treated with exposure therapy, where the person is exposed to their fear in a controlled setting.
