A physio is like a Doctor Who deals with muscle problems and injuries. They often work closely with sports people and most gyms have a physio on site.
You need to be able to be confident and have social skills to become a physiotherapist.This is true, but first you need a good working knowledge of Anatomy & Physiology. Then learn Body Mechanics. Get old textbooks and study at home. This will get you off to a flying start.
what you can do is do about 15 or mins of yoga, or any kind of other back exercise but yoga is better. also, it can be your bed because of the spring pressure. in most cases you cant do anything because you been injured badly in your back.
