I've got a pain in my chest when i breathe in deeply but i noticed when i get up from a lieing down position it also hurts can this be muscle related?

Yes: Unless you sustained a recent rib cage injury or strain, this may be a pinched intercostal muscle or nerve that runs between two ribs and a deep breath or any other rib cage motion causes a sharp,fleeting pain. These situations usually resolve on their own after a few days. See your physician if pains persist or worsen. Avoid stressing your rib cage until pain resolves.
