Have been to doctors for so many ailments and absolutely not one positive thing to say. going to try hp.. mayo clinic told me to come home and do pelvic floor exercises. on a cpap machine for 8 yrs now and I swear it is causing me to have chronic stomach problems.. diarrhea... hands and feet swell, muscles ache... I hurt from head to toe, is easier to say... have nebulizer.. would like more info on % of food grade hp? how often to use?
