i am not a dr but from what i have read and understand full body rsd is when rsd has spread to all the body parts externally i.e. hands, feet, arms, legs etc, as well as internally i.e. heart, lungs, liver, kidneys, etc. i hope you don't have full body. i hope that none of us ever get full body rsd. i keep praying that with raised awareness of rsd, a cure will be found soon. soft hugs to all.
